No en passant move, while in check in blitz?

My opponent was not able to make an en passant move while he was in check, later in the game he was able to do the en passant. Weird.

At move 28? strange!

Send feedback if this is the case, Admins will want to fix if this is truly a bug.

P-

The only en passant capture I can find here is 30. f2-f4 g4xf3, which I think is legal.
