Hi, for some reason my plex stops playing after 4 hours of no interactivity. i like to play shows while i sleep but keep waking up to a movie which has stopped playing after 4 hours. I’ve searched the options but could not find anything relating to that. i also checked my Roku TV and again nothing is there,

after further research it was my roku settings.
