Issues with audio on zoom mobile app

Hello,

About two weeks ago, participants in my zoom meetings began complaining that they could not hear.

This was strange because I could see the mic icon next to their names indicating that they were connected to audio.

My wife tried to join the meeting this morning using her Samsung A51 and she gave the same complaint.

After taking a look I noticed that when I joined the meeting and then joined audio, I could hear for a short while. Eventually, the sound would just disappear for no apparent reason.

What I observed was that the speaker icon in the top left also disappeared. I could hear nothing on the device but it was still indicating that I was connected to audio.

I could un-mute and speak and still be heard but I could hear absolutely nothing on her device.

I have already uninstalled and reinstalled zoom but it is the same issue.

I have tried using headphones but the problem is still there.
