Issue In Audio Call

Currently I have Two React-native Application A and B and i am Using LiveKit for Audio Call functionality
My A and B both application is working Great in android Devices
And
A in Android and B in Ios is working
B in IOS and A in Android case Android audio is going to IOS but IOS Audio is not receiving in Android App

Both implementation is same
Then why the issue came

It’s difficult to say, this sounds like it is only an issue with a single app, and only present on iOS. To me, that points towards something specific in the broken app (either an issue with the app, or some issue in the framework resulting from how it is being called)

If it were me, I would start with the known-working React Native sample, GitHub - livekit-examples/agent-starter-react-native · GitHub, and slowly add features to make it resemble your non-functioning app, to isolate the root cause.
