Renewing Greencard

I filled (Jointly) for ROC in July 2020 and my service center is Potomac (YSC), I never moved/changed addresses. I have been following up with the case but the last update was January 22 2021 when the status was changed to "The fingerprints relating to your Form I-751 Petition to Remove Condition on Residence, were Taken" and since then there hasn't been any other update until this afternoon when I check and saw this update " On August 26, 2021, we transferred your Form I-751, Petition to Remove Conditions on Residence, Receipt Number YSC **** **** **, to another office for processing and sent you a transfer notice. The notice explains why we transferred your case. Please follow the instructions in the notice. If you do not receive your notice by September 25, 2021, please go to www.uscis.gov/e-request to request a copy of the notice. If you move, go to www.uscis.gov/addresschange to give us your new mailing address."
Please has anyone received this type of update before and what would be the next step(s)?

Looking forward to your responses, Thanks all ..... Please see below my timeline.
