I did manage to solve it. I don't remember the exact steps I took but it had to do with the option I selected when connecting the guest device. For some reason AMD Link kept making the device I wanted to stream to the host computer. This was really frustrating because I never selected that and I always started AMD Link from my intended host computer. Anyway, so when I started AMD link on the guest device, I had to select the other option. Then it worked. I think the order I started the process with mattered too. It's been awhile and I don't use it often, partially because of how non-user friendly it is.
