Concurrent F1 - H4 EAD. H4 approved but no EAD

We had applied for a Concurrent F1 to H4 + EAD along with H1 extension (premium). April 24 2020 at Vermont.
We had an RFE on the EAD which we responded. Fingerprints were taken on Feb 11. Now H4 is approved but EAD is still pending -“Received response for RFE”. Has this happened before? What is the course of action in this scenario
