Last update broke playback resume

My Xbox One has been working fine with Plex for some time now, but recently (possibly with the last update) I cannot resume playback on any video (ie stop movie halfway, then attempt to resume from last position). The “resume playback” button is there, but it just goes to the beginning of the video.

I’ve ruled out the server being the cause, as my Plex iOS app allows me to resume playback.

Hi, please post logs of an incident when this is happening.
