S24 - Whatsapp mutes my microphone when I switch to another app or display times out

[Members_bRiF8XO]

Hello, I've just got a Galaxy S24+ and have noticed that when I'm on a WhatsApp call and navigate anywhere outside of the app it will mute my microphone so the person I'm on a call with can't hear me, though I can still hear them. It also happens when the display turns off.

I have seen a couple of posts about removing whatsapp from 'sleep' or 'deep sleep', but when I check the sleeping apps WhatsApp isn't there. 

Any ideas are welcome. Thanks!
