hey @yong
Can you let us know the version of @react-native-async-storage/async-storage so that we can investigate it further. Also, can you check whether you have initialized CometChat before using any UI Component. You can also try to reinstall the pods in IOS because I think the AsyncStorage is not installed correctly.

Warm Regards,
