No audio received or transmitted in non-hosted call?

Can anyone help me understand why my profile "Matt" in a zoom meeting today was unable to receive or transmit audio? I was taking a zoom i was not hosting and using my Android.

I know there are a lot of technical things going on and i'm sure it was just a glitch.  The zoom server wouldn't allow me to upload a screenshot which is well below 5MB.

Thanks,
