Awaiting Guest ID

I was looking at my airbnb calendar and noticed there were three nights blocked out for next week. I never received notification of the booking. There was a message from the guest saying she was looking forward to the stay but the calendar said Awaiting Guest ID and As soon as Maureen verifies their identity, this reservation will be confirmed. If they aren’t verified within 4 hours, these dates will be opened for other guests. That was at 9 am this morning. It is now 8 hours later and the dates are still blocked but no booking. Has anyone else had this happen?
