My Beelink Mini android box got outdated I think. Amazon Prime and Youtube TV app used to play properly in it from years. Now Amazon Prime Video says unsupported and Youtube Android TV app does not even open on it. The old version opens up properly but it stops playing videos after a second of loading up. It even stopped playing any resolution from 1080p-144p and used to buffer a lot for no reason.
I tried Youtube addon in Kodi and it played a 720p video without any buffering. I don't like Kodi interface though. Probably will shift to playing Youtube and Amazon Prime videos in my NUC now.
