To be honest we see a lot of complaints on this software development doesn't seem to be moving out of beta level software either. I don't know how serious AMD is really working on this tech.
That being said if they say they support it, it should work. However the original store mi software was completely replaced by the store mi being offered now.
So maybe some of those claims are just non updated web pages where the old software did work and now does not. I have no idea. Ask AMD support they should be able to at least tell you if your hardware is or is not compatible or if the software has a bug.
