Latest plex server update on NAS causing 4k content buffering every 10 seconds

Server Version#: 1.25.8.5663
Player Version#: 8.31.2.31546(62043fa3)

Its direct play. Not even transcoding but buffering a lot.

Same here with Synology. Went back to last workable version on my Nvidia Shield.

How to rollback to previous versions of plex?

I did this, I need to rollback from the latest Plex update and it worked great and it’s easy.

Mine is asustor nas.

On my Shield I deinstalled the Plex app and replaced it with the previous one, which I downloaded from APK-mirror website.
