Been unable to log in to Coinbase for weeks now, because the web site keeps sending invalid SMS codes.
After navigating through the maze of FAQ's (No faq for this problem), I found their email form. After about a day they reply with the answer to a problem which I don't have
They tell me all kinds of reason for why the SMS'es might not reach me.
COINBASE: THE SMS'ES YOU SEND ARE RECEIVED, BUT THEY ARE INVALID!
Seems the reply I got was automated as well, based simply on the categories you have to choose. Very disappointing.
