i have an iphone 15 pro max, that i can plug in a external ssd, and copy videos to infuse.
is there a way that if i copy a video that plex also has, and i watch the copied video from the ssd, will it sync to plex to say i watch the video?
Unfortunately, playback progress cannot be synced in this way. You can however mark Plex items as watched in Infuse and that will be recorded on the Plex server
