Shield TV Pro is slow and unresponsive in Plex

Server Version#: 1.25.2.5319
Player Version#: 8.28.0.30077

I got a Shield TV Pro recently and for the most part it’s the best 4K streaming device I’ve used. But in Plex I’m having a lot of issues. They may not be specific to Plex, but it’s the only app I use on it.
From time to time the system will totally freeze requiring a hard restart.
Often, just about every day I use it, there are times that it will take 5 seconds, to over a minute for the system respond to a button press on the remote. If I’m patient it will eventually sort out whatever the problem is and will go back to mostly normal, if not a little slow, operation.

Also I have the same issue as another user posted here.

I’d like to use the server capabilities to run a backup server, but can’t imagine how that would work given the performance issues.

Any suggestions?
Thank you!

You and me both buddy. Plex just freezes and locks up, and can’t find a reason or solution to this problem.

Your not clear on weather Plex Server or Plex Client that your having an issue with.

Are you referring to me or Plex_n_Chill?
For me, it’s definitely the Plex client on the Shield. A force quit of the Plex app always resolves the issue. None of my other Plex clients have issues like this.

Are you running a beta or the official from the Play store? Might try a different version.

Running the official from the play store. Do you have to side-load the beta, or do you sign up for Beta access in the Play Store?

I download it and copy it over to the shield. You can enable network access in shield and then you can access it \IP Address from a Windows machine.
