User Disconnection Issue After Migration to React Native

[L-Weisz]

Hello,

We are currently migrating our app from a native Kotlin/Swift implementation to React Native. However, we are encountering an issue where users are being logged out after updating the app.

In our native Android app, we used firebase_bom = "33.1.1" (auth version 23.0.0).
In our native iOS app, we used Firebase Auth version 10.16.0.

As part of the migration, we are now using React Native Firebase 20.4.0, which relies on Firebase Auth 10.29.0 for iOS and firebase_bom = "33.1.2" for Android.

Would you have any insights into why users are being disconnected after updating the app? This issue is significantly impacting our users.

Thank you

I don't understand why you would be doing a migration, but migrating to old versions?

There were some issues with deserializing user status on iOS that were fixed in current versions (that is, firebase-ios-sdk 11.7.0+ - the most current version as of now).

I'm not aware of issues on Android, no one has mentioned any at least.

I have no particularly special insight into either though, sorry. I can say that react-native-firebase uses the exact same native SDKs so users should be recognized

Thanks for you answer,
To be more clear : I am not migrating to an older version,
we are migrating from :
iOS (Swift) 10.16.0 -> iOS (React Native) 10.29.0
Android (Kotlin) 33.1.1 -> Android (React Native) 33.1.2

For iOS it seems that react native does not use same caching system as the iOS native

This is an assertion that defies the evidence.

firebase-ios-sdk is on 11.7.0, firebase-android-sdk is on 33.8.0. Both are contained in the most recent react-native-firebase release. Consult the changelog -> https://github.com/invertase/react-native-firebase/blob/main/CHANGELOG.md

it appears to me you are migrating to an old version.

This is an assertion and requires evidence. firebase-ios-sdk is still doing the same thing under the covers inside react-native-firebase as it was doing in whatever Swift code you had. I believe it uses the user's keychain to store auth data, but it is actually unimportant what it does as it is a black box you simply call in to - and it's the same one provided by their same auth code

Hello @mikehardy thanks for taking the time to answer
indeed we saw that it was our AuthenticationContext that had an issue, we are now able to maintain the connection between native and react native application
I am closing this post as there was no issue related to the package :)

Happy to hear you found the issue! Good luck with your project
