Jitsi meet not working on Android mobile

We have downloaded JitsiMeet app from App Store on our Android Mobile.
We are not able to join any Room which created on Web App on Desktop.
Our Mobile is not able to connect/joing to an existing running Room

Please help.

We’ve had a couple of bad updates. Which version are you running? What server are you trying to connect to, and what issue do you experience?
