Receiver cannot hear me in calls (microphone tests OK)

Not quite sure when this started, but have recently noticed that when making phone calls the receiver of the call cannot hear me. Problem occurs with three different ‘phone call making’ apps on the phone.

I ran the FP4 automated test that checks the speakers and microphones and they all pass fine. Additionally, a Sound Recorder app on the phone is able to record me clearly. All the ‘phone/dialer’ app status pages show that they have Microphone access and the latest OS updates have been applied - so I am out of ideas at this point.

Anyone had a similar problem on the Fairphone 4?

Thanks.
