Same here with LG OLED77G48LW Often it stutters too after skipping forward, until I pause for a few seconds and it’s fine The App-Restart feels like running out disk space or memory, like mentioned If I remember correctly, 95% sure, it all started after the last major update of the TV itself! The…

Cant believe this major issue is not adressed! Its litarrely game over for plex on LG at the moment. I cant believe it worked fine for years on my other LG tv and on my new one in the living room, but this big WebOS release ruïnes everything. Force play is even worse. How can a 5k tv have so little …

The media player doesnt find any files, so cant test that. Wierd and very weak local media player delivered by LG

Has there been any official response on this from Plex or LG?

Same issues here. LG C4 77. App crashes every 20min or so playing 4k HDR content. App becomes unusable before crashing.
