I'm in the same boat as you, @Utah123 - I filed I-751 in Nov 2020, was a dreaded YSC, but then my case was transferred in Sept 2022 following my N-400 (Orlando) application. I was at the biometrics stage when my case was at YSC and am back there again now my case is at (I assume) NBC.
Can anyone weigh in? Is it unusual not to move to the "ready to be scheduled for interview" status?
