Just chiming in so those still waiting know they're not alone.
My original Biometrics appointment was March 25. It's been more than 90 days since the Charlotte ASC reopened, but I still have not received any word on a rescheduled appointment.
I reached out via USCIS website a week ago, got a long canned response around Covid delays and reopenings, but nothing addressing my specific case.
The wait continues.
