Hi @skychavda9 ,

Thanks for the post and pardon the late response. Based on the message, it seems like the React Native wrapper is not using our SDK in the main thread. Since we do not have a React Native wrapper, you might need to contact the developer who develops the wrapper you are using and update this part.

Thank you!
