Hi there, just stumbled upon this thread! We went through the process and were approved in December, would be more than happy to help out or answer any questions. Our timeline was as follows:
I-130 Sent: 2/16/21
I-130 NOA1: 2/16/21
I-130 Approved: 6/2/21

USCIS was processed at the Nebraska Service Center. The timeline far exceeded our expectations and we were one of the lucky ones I guess. No hiccups and we filed everything ourselves. Keeping you in our thoughts and hoping for a prompt finish!
Edit: Rereading your post, have you been documentarily qualified from NVC? If so, what was the date?
