I have an iPad 4 where Plex will randomly start playing a video I may have paused on previously.
I was watching the last episode of fringe, episode 13, from my computer when suddenly my iPad resumed episode 3 of the 5th season. The passcode lock is set for an hour and I did have to unlock it. I could see the play controls for Plex on my lock screen but nothing about the episode that was playing. When I opened the app it kept playing like normal as if I had chosen to play that episode.
I had this happen on an earlier os version a couple times, but I thought because it was jailbroken that may have a been the cause and is actually one of the reasons I formatted back to factory settings.
Current setup:
Plex 4.1.1
iPad 4 - MD514LL/A
iOS 9.3.2 (13F69)
I took a video of this but if there are some sort of logs I can send I'd be happy to send them.
Thanks.
