i have similar situation.
Called USCIS, they say we should be notified soon about it.
I ask - how many days will take?
they say - since ALL USCIS office were closed, a program will be held to work on the cancelled appointments.
also, i am not sure if he did, but initially he said, we can send a reminder to the office about your case, so I am not really sure if he did or not.
Does not harm to call and find out at the customer service center.
