I was booted off YouTube streaming on my AppleTV. Then my main account disappeared from iOS GMail app, even though a secondary GMail account was still there. Was afraid my accoutn was hacked. My GMail password is unique and quite long compared to my other pw so I doubt someone could find it. I added the account again on the iOS GMail app and then signed in YouTube and it was back to normal... hmm.
