No, this occured to me just yesterday.

Might have something to do with your account's 'rights.' Sometimes if your channel hasn't had some sort of email verification, you get limited features. Not sure why it would pop up now instead of before though 

Hmmm, okay. Im using a channel that uses the email as my main account, so maybe it has something to do with that.

Kinda strange because i still have the rights do costum thumbnails and stuff.
