Hi @chetangodiya-simformsolutions,

A few questions:

I assume by event, you mean meeting?

Can you try reproducing on the demo app? If this is not reproducible on the demo, can you provide the diff?

Can you provide logs?

Your error:

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[MeetingObservers remoteVideoSourcesDidBecomeAvailableWithSources:]: unrecognized selector sent to instance 0x600000757860'

indicates you are trying to use a newer release of the iOS SDK that supports remoteVideoSourcesDidBecomeAvailable.

Currently this React Native Demo only supports the AmazonChimeSDK and AmazonChimeSDKMedia versions linked in the README.

However, If you feel inclined you can add those APIs yourself and open a PR.

@dylonChime

the above issue is resolved now by using the sdk mentioned in the README but the issue is remains

[dylonChime]

I'm glad to hear it works. I'll close this for now. The README will be updated when we officially support newer versions.

[chetangodiya-simformsolutions]

@dylonChime only the error you mentioned was resolved the issues of black out attendee tile is remains

[ziyiz-amzn]

Can you try the RN demo app following the updated README? The latest version compatible with RN demo app for iOS is 0.19.1. It comes with CocoaPods support. I cannot reproduce this issue using the demo app.

[chetangodiya-simformsolutions]

@ziyiz-amzn i found the issue after installing the sentry and here what i found please click on the below line

**Invariant Violation Unable to find node on an unmounted component. mechanism onerror handled false
