Help & troubleshooting for channels on your Roku device, including adding/removing channels, logging in to, authenticating, or activating a channel, channel-specific playback issues, assistance contacting channel publishers to report issues, and adjusting channel-specific settings.
Every few months all of the Discover Go channels, A&E channels, Fox channels, History channel and the Hallmark channel to name a few, auto log off (or refers to time out). This occurs on multiple Roku devices (Ultra and Stick).
Basically its all channels that I authenticate thru Philo as my TV provider while some channels are authenticated thru YouTube TV.
To re-authenticate numerous channels, on multiple devices is very time consuming, every few months.
