When choosing a channel to watch we are getting this error when pressing the trackpad on the channel (which normally takes one to the channel/program info where you can choose channel as a favorite).
Oops. Document Not Found on Stack. Maximum call stack size exceeded.
We can get around this by pressing the play button instead.
Also, while here, and related to the panel. The program schedules do not update when one presses the menu button to go back. This applies to both the favorite screen above (if that works [back once]) and to the channel listing [back twice]. Then if one presses play, the episode isn't available since it's often hours old. Has been this way since we installed emby last spring.
I played around with this some and installed emby on a RaspberryPi 4 with 4GB. It was running version emby 4.3.0.15. Had no problem with play functionality described first using the PI.
Emby Version 4.3.0.16 (also did with 4.2.1.0).
