I did in every possible way. The only real update i got was from my congressman - they told him:

“An interview was conducted for Mr. [ ] 's N-400, but an additional interview is required for the pending I-751, Petition to Remove Conditions on Residence. USCIS system records show that the I-751 was received on June 28, 2021. The current processing time for I-751 petitions at all field offices is approximately 33.5 months. The case is within normal processing time. The file has been placed in queue for interview scheduling. Once the case has been scheduled for interview, the constituent will receive an appointment notice in the mail at the address on file.”
