All apps/channels painfully slow after update 9/19/2023
After the most recent update to my TCL 75R635's apps are extremely slow. Never had an issue in Prime video, Netflix, etc but now there's a tremendous lag when navigating the apps. Moving around the home screen to choose an app, setting, etc is fast and fluid. Once I enter ANY app, everything is painfully slow.
Tried using the not-so-secret code on the remote where the TV reboots after 30s or so and that changed nothing. Did a complete factory reset much to my dismay and still nothing. This happened IMMEDIATELY after the most recent update from 9/19/2023 12.5.0 build 4165-88
Anyone else have this issue? I found similar older topics from Google pointing to these forums and folks had similar issues where the common response was factory-reset or the not-so-secret code and the results have been hit or miss.
Any help would be greatly appreciated. Even YouTube is nearly unusable just navigating to a video - nevermind searching. My Fire Sticks, WebOS and AndroidTV devices are fine - has nothing to do with connectivity.
