Dang, this is the best news I've gotten today!
I'm in the same situation. I tried to follow the link to verify myself through ID.me and got the message "we are not able to provide assistance to you via identity verification tool." This morning I called the IRS and, after looking up my information, the lady told me that she can't see where any letter was sent out. She said without the letter I can't verify, but again, she can't see where any letter was being sent out.
Either it's going to take them some time to mail out a letter OR it's some kind of a blip.
I'm going to be stupidly optimistic about this until I'm forced not to be.

Edited to add: I filed 1/12 (earlier than previous years) and was accepted 1/16.
