It should be on the Home page right hand side.
It should also appear under Settings>System
It should show up even when you have the latest drivers.
(Note that I did not make any hardware changes and never have problems opening the software. Still, my symptoms agree 100% with you problem description in the subject line)
I have been experiencing the same thing for the last few weeks (same for driver 20.8.1). After using the AMD cleanup utility followed by a fresh install, the drivers show for a few hours, but disappear again later, never to be seen again. A couple of days ago I reported this via the built-in bug reporting tool, but have not heard back. I will post back if I ever get an update.
Note that the driver information and update options disappear from the home screen as well as from the driver page (gear... Software&driver). Once they disappear, they never appear again until I use the cleanup utility in safe mode followed by reinstallation. Sisyphean!
Here are screenshots comparing before and after for both instances. You can see from the driver page, that everything is identical in terms of version.
Update: So I did another cleanup and then installed 20.9.1 yesterday (Released 9-16-2020. How would I know that there is yet another new driver if the app doesn't tell me??? 
)
Even though I could not find any relevant entry in the release notes, so far it seems stable and the driver information has not disappeared yet. Looks promising! I'll post back if the problem reoccurs.
Even though it seemingly took a bit longer for the problem to reappear, the new driver did not fix the problem. See post below.
SInce I am the only one talking here, can I assume that nobody else has this problem? So what's different here? I still have not received an update from bug reporting tool submission from over a week ago... 
. Is this something I should expect eventually???
Note that even with the driver info missing, everything works just fine....
The problem is both cosmetic (I cannot see my driver version) and functional (there is no update option)).
Thanks for the clarification. I guess I had some misconceptions, confusing the bug reporting tool with actual customer service.
It takes many hours (typically overnight) for the driver info to disappear (My power settings are to never go to sleep). Since everything else works perfectly, I have given up doing the mentioned "temporary fix", because it simply does not last. I have also update all the AMD chipset drivers, but that did not help either. From now on, I'll just occasionally check the AMD site for driver updates. Hopefully others will also have this problem and report it. (Searching google there is quite a selection of similar reports dating back many years. Often a clean install is the suggested fix, but that apparently does not work for me).
Another maybe related observation is the strange thing that this morning the system tray had three AMD icons, but two disappeared when I hovered over them. Looks odd. <shrug>.
Thanks. Fast startup was actually disabled. However my computer never goes to sleep and there is no restart involved before the driver info randomly disappears a few hours later. (I also understand that fast startup does not apply when rebooted, just after a shutdown, which I never do)
The way I understand it, windows driver updates cannot be directly configured on windows home (that's what I have). However, we are getting warmer!
NEW observation: The drivers show fine for many hours, but as soon as I got to windows update and "check for updates", the screen flickers, "Radeon software" restarts, and the driver information has now disappeared.
The windows update log has the following odd entry:
(And a quick web search for that shows others with that problem (example from 3 days ago!). Note that this number is similar to the OpenGL Driver details, currently 26.20.11000.14736 but very different to all other numbers listed)
Obviously, I need to somehow prevent that installation. I'll look into your links further, maybe using the regedit method.
My windows configuration is pretty plain stock vanilla, so why would windows update even do this (apparently only on my rig and very, very few others)? Maybe this is something that could be fixed by Microsoft and/or AMD eventually.
I'll check a few more things.
OK, narrowed it down to Dell!
Searching for that number, it shows up in several places in the registry. Here are two of the keys:
[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0000\Software\DELL\ManageableUpdatePackage\AMD_MUP_PA_Dell\Version\Version]
"AMD_MUP_PA_Dell"="26.20.13002.133"
(and quite a few more, differing just by the underlined number: 0001, 0002, etc.)
[HKEY_LOCAL_MACHINE\SYSTEM\DriverDatabase\DriverPackages\amdkmdae.inf_amd64_d00f70e4b774c278\Configurations\ati2mtag_Polaris10\Driver\Software\DELL\ManageableUpdatePackage\AMD_MUP_PA_Dell\Version\Version]
"AMD_MUP_PA_Dell"="26.20.13002.133"
I wonder if this information is sufficient to fix the problem somehow?
(System is a Inspiron 5675 , Ryzen 7 1700X, Radeon RX 570)
So here's the fix I finally used. Maybe it will help others with certain Dell hardware.
(Sorry for the long delay. I just disabled windows updates, but that has ended and the problem reappeared, of course. This is "Windows Home", which has fewer direct controls. This solution is relatively easy, at least easier to the links that have been quoted by others. No regedit, no commandline, no scripting. The fix is very specific and will not prevent any other driver updates)
- Pause windows update.
- Reinstall the newest Adrenalin driver doing a full reset.
- Download and run the special tool from microsoft found here.
- Select the AMD extension driver 26.20.13002.133 to exclude it from windows update (See image below). Note that it won't show if it is already installed. Only after steps 1&2 it will show because it is scheduled to be installed at the next update.
- Now we finally can un-pause windows update and safely update automatically again.
- Surprise! Windows update will no longer install that wayward driver that corrupts the Radeon software, causing it to no longer display driver information!
Here's a screenshot of the microsoft tool and a screenshot of the final tool report.

Another way to avoid this is to unplug from the internet when you install the driver. When the install process uninstalls the driver, being offline keeps Windows update from checking the online Windows repository and trying to insert it's own driver while the AMD driver is trying to install.
That's why I said to pause windows updates before updating the radeon driver. The driver install typically works fine and the problem does not occur right away. In only shows hours or days later (or as soon as windows update is initiated manually). I am not sure if the quoted tool will even show the problem driver if it cannot connect to the internet and I am not going to test. 
. I recommend not to deviate too much from my instructions.
