I’ve been having the same problem recently since an update. I used to be able to scan far forward in a video by clicking and then swiping right and it would start playing immediately. Now I get the spinning wheel when I do that. The only work around its to hit the menu button and then start the video again. It will then start where I intended. It’s been really buggy when skipping 10 seconds too. It will freeze, audio will cut out, or I get the spinning wheel. Plex used be solid and work as intended on Apple TV. Netflix, Prime and all other apps scroll and scan properly. Every update this gets worse!!!
