Ok, I'm stumped.
So is this a known feature, or am I just lucky? Anytime I want to watch something using the YouTube app, I need to log in. Unfortunately, it seems to randomly log me out all the time - forcing me to hit "sign in" again, often multiple times, every time I want to select something new from my list of subscriptions. The app literally won't stay logged in for more than 60-90 seconds most of the time, which makes picking anything from my history or subscription list difficult.
It didn't always behave this way, but now I can't find any way to fix the frequent logout issue. Any tips or suggestions?
