For about 2 weeks now I have been able to view any MP4 videos on Plex. I click on the Play button and a window will open with the line showing progress through the video at the bottom, but no video appears on the screen. Movies still play, but small videos mostly recorded by my phone will not. They did work previously, so I don’t understand why they are not working now. I would appreciate any ideas about how to fix this issue.
The update I just installed seems to have fixed it.
