Call recording not working in any mode with moto g6 play

This paid app can do it without any issues. Crystal clear sound of both sides of conversation, no root required.

I even tried "mic" too but still would not record anything of the other side :/

That's sad because I'd rather have a open source software recording my calls than this unknown party... if they can do, sure you can too?
