Disabling Background Noise on Android (posts have been for desktop)

I have latest download for mobile app Android

Enabling Original Sound does NOT disable background noise suppression.

Starting new meeting, setting switch to Original Sound on or off.  Neither disable suppression of noise.

This used to work.  Now Original Sound switch makes no difference in recording.

Also app does not have Original Sound for Musicians instead of Original Sound

How do I do this on MOBILE APP - please no desktop instructions.
