Certainly I have sent them an e-mail which is the only mode of support that I can see.  It is only reasonable to allow at least a day for a response, and that period of time has not yet elapsed.

I agree that only Coinbase has the ability to explain the discrepancy between the automated e-mail they sent, and their web site.  In this case I just wanted to find out if anyone else had noticed the phenomenon since this particular failure mode seems notable to me.  The main reason being that it will help me choose the appropriate attempts at further interactions with them.  That is, if this is a common problem that is automatically resolved then I won't bother to try to follow up.

I do hope that someone at Coinbase would notice this thread and participate in it since it would almost certainly help both myself in overcoming initial issues, and also very probably would help others in seeing the quality of their support efforts.
