H4 COS and EAD pending for 10+ months

My wife filed the L1 to H4 COS in June 2020 and H4 EAD in July 2020. She took the biometrics appointment on early March 2021. It has been 10 months since the petition was filed. However, they are still showing as pending on the USCIS website.

Raised an out of normal processing time request to USCIS in March. USCIS replied “U.S. Citizenship and Immigration Services (USCIS) records show that your case is currently pending adjudication. However, we have had to perform additional reviews on your case, and this has caused a longer processing time.”

Is there anything else we can do at the moment to expedite the request?
