This is a bug that was fixed early but is now back or a new one that demonstrates similar problems. You can find an early thread that I participated in HERE
My server is running Linux Ubuntu 20.04 LTS
My android tablet is a Galaxy Tab S4 Build QP1A.190711.020.T830XXU4CTF5
Problem: When syncing movies to my tablet the file size on the tablet after sync is very large and watching the video shows no sign of reduced bit rate. I have tried several full length movies and set the sync quality to .3 Mbps which should be obvious when compared to the original movie at 20-30 Mbps. In addition when looking in the sync manage tab, the size of the movie is equal to or very similar to the original size (15-20 Gigabytes in size at .3 Mbps for example). All movies and TV shows are 1080 or 720 resolution.
As I mentioned the Plex forum thread above shows that this issue has existed before and seems to have come back in the latest builds. I am happy to help track this down.
Yours,
James
