On our LG G1 OLED, when watching a program on Binge, the Binge app restarts itself every 20 minutes or so with a message about needing to restart to free up memory. Power-cycling the TV doesn't fix the problem, nor does running the "Memory Optimiser" function from system settings. None of the other streaming service apps we have on the TV have this problem - Prime Video, Stan, Netflix, Disney+, Britbox, ABC iView, SBS On Demand, Youtube. Those are the only other apps installed on the TV. I've checked the LG WebOS version and checked for app updates, and everything is latest version.
If I run the Binge Android app on my Chromecast with Google TV, it works without any problems when streaming the same programs.
