Yes I’m having the same issues. It’s definitely a thing that crept up in more recent versions. The silence is deafening with this.
Using Plex on Android TV is currently a mess. Collections take like 5 full seconds or more to even show up underneath movies and music albums under artists seem to take even longer.
This is a severe issue and affects lots of parts of Plex. I’m starting to get various glitches because of these timeouts (the whole artist library section stop responding, server doesn’t show up in “more ways to watch” etc).
