Bluetooth Mic not working

[hogen20]

I recently bought a bluetooth headset. I can connect it and everything works correctly including the controls for volume, play/pause, etc., except that my note 8 will not register any noise from the microphone. It still uses the phone's mic.

This is the model of headset: https://www.amazon.com/Mpow-Bluetoo...ag=hawk-future-20&ascsubtag=UUacUvbUpU6316913

Any help is appreciate.

Thank you
