@Maunebei28 Is your YouTube working again? LG Alessio
a year later
@Dikesseuf74 Try “Reset Box” (Settings -> System -> Reset TV Box).
If the app still won’t start, do a reset with the paper clip on the bottom of the TV box while the device is running.
The settings are not lost, only the app logins have to be recreated.
@roku73 Thank you. I haven’t thought about reinstalling the box yet. It’s working again now. Thanks for the quick reply
