YouTube app logout after some days of using...

hey, I'm using my Apple TV to view some YouTube videos and I have a youtube account for abonements etc. after a several time of use for example 2 days, the Apple tv YouTube app shows me that I have to login again and that's not very handy.

Does anyone else have this problem? Is there a solution to keep the login active for all time until I change passwords or something like that? Hope to hear for you, thanks!

bbest regards, Torben
