Why do I keep getting signed out of my YouTube app

I have a sharp Roku TV model LC-43LB481U, and I have to do this uninstall system reboot, reinstall every month or so. Why does this happen? This shouldn't happen. I literally signed into the YouTube app, flipped to the home screen to change settings and went back to YouTube and it logged me out. So I'm in the course of doing another one of these uninstall reboot install cycles but I shouldn't have to do this every month for YouTube to work.

I was having the same problem for months. Recently I realized that my Roku account was registered under a different email than my gmail account. I switched the Roku account to gmail and I have not had a problem since then. I don't know why.

Welcome, and thank you for posting here in the Roku Community, ulonzui.

Thanks for letting us know about this. No worries! We're here to suggest some troubleshooting steps and provide further information about this.

Firstly, can you please confirm if your Roku TV recently received any software update prior to this happening that might have triggered this issue? If not, kindly follow the steps provided below to see if this makes any difference:

1. Remove the channel: navigate to your Home screen, move to the right, highlight the app, press Star*, then select Remove channel
2. Perform a system reboot: navigate to your Home, select Settings > System > Power (skip if unavailable) > System restart
3. Re-install the channel: navigate to your Home, scroll and select Store, look for the app, then press Add channel

If the issue persists, we highly recommend directly reaching out to the channel provider for additional assistance as they manage and maintain their app on the Roku Streaming platform independently.

I'm getting rid of my roku tv and going back to LG way better, less issues and no more stupid ads! 

I found that if you go to guest, then sign in, it keeps you logged in for a while but it will stop.
