Here we are four months later asking the same question I first asked back in September, why won't Youtube stay logged in on my roku express+ streaming device.. It stays logged in on my Samsung tv as does YouTube tv, but for whatever the reason it cannot stay looged in to my Roku, any of the roku devices I have nor my brother.. I wonder why that is?? I have contacted YouTube several times but it is beyond their ability to care so I am asking you, is there a way to make these services stay logged in that I don't know about?? am I holding my mouth wrong?? what gives?? last night I found I had to log back into my youtube accounts again and did so but now when I go to get off of them instead of going after the exit link that there is when you push the back button enough times, I have instead decided to take the flower route and hit the home button, that gets me out of the YouTube and the YouTube tv services right now instead of going looking for the exit link.. I figure it's likely going to need logged back in no matter how nice or a butt I am so might as well feel good about treating their crappy app like ... not very nicely.. And like I said it works perfectly on my Samsung tv, I logged into both services back in September and haven't had to re do it since.. Why that is I have no idea, maybe it is time to contact roku, and see if they are to blame for this situation.. I still think it is YouTube fault though.. Maybe it's time to buy a different streaming device and test my theories out that way..
