Plex won’t play on s21 ultra 5g
On Wifi internally on your LAN ? On 4G/5G/LTE connection ?
What Plex version?
You really have to going to do a bit more effort if you want people to try to help you out…
My Ultra S21/5G works just fine with the (latest) Plex app, both internally on my LAN and “outside”
For me it was playing before updating to Android 12 OneUi 4. Now it doesn’t work anymore. Playback won’t start. I subscribed to the beta on PlayStore to see if newer version fixes this but not. 
Oh, I have same issue.
Not play any videos after upgrade to Android 12 (OneUI 4.0).
It’s show library, I can click on play video…
but after that the circle with the load spins endlessly.
Can play videos when switch to external player in settings.
All in my local net (over wifi). All other devices play videos normally.

I’m having the same issue after updating my S21U to Android 12.
Stopping and opening Plex didn’t solve the problem.
The only way I can get the app to play content stored on my server is to restart my phone. Then the Plex app works; but when go to play content 24 hours later,I can’t stream again - unless I reboot my phone. 
BTW. I even tried to have Plex on my phone Download unwatched episodes thinking I could avoid the video not playing
While I do have 3 episodes of a show downloaded on my phone,I can not play t those videos either - again, until I do a full system reboot.
Had anyone solved this issue? Now I have updated to One UI 4 Plex is basically useless.

Maybe changing the screen resolution will help? I changed mine from WQHD+ to FHD+ and videos are playing again, a bit of a workaround though rather than a solution…
I’m having the same issue and it seems I’m not the only one.
Phone Samsung S21 Ultra 5G with latest Android 12.
Here is the reddit thread with the video: https://www.reddit.com/r/PleX/comments/rcwe4p/plex_for_android_completely_unusable_works/
from browser I can watch the movies, but when trying to launch from plex app I just see circle running around…
