@PanasonicUK @YouTube not sure why but why is it that adverts end up breaking the youtube app on Panasonic tv (Firefox tv) either it can’t handle a ad less than five seconds or can’t load the ad stopping you watching full stop.
Thanks for trying those steps. As a next step, please login to the account/device experiencing the issue and send a feedback report here: https://www.youtube.com/tv-feedback . You may not receive an individual response, but the details will help us identify and fix any issues.
