I have the same problem. Technical support are just ignoring that problem, don't want to do anything with that.
Main thing is that built in recording function is awful. Quality of recording is bad, some noises on the record, files size is big, and sometimes recording is suddenly stops, even if you have enough free space.
And other apps don't want to work together with that xiaomi recorder on the board.
I don't want xiaomi recorder!
I want another app!
But xiaomi don't let it work.
