FirebaseAuth not storing logged in user

[jkwiecien]

I've implemented Firebase sign in via Google sign in. Flow looks fine most of the time. I monitor it with this piece of code:

    val userFlow = firebaseAuth.authStateChanged
        .onEach { debugLogDefault("user collected: ${it?.uid}") }
        .stateIn(
            repositoryScope,
            SharingStarted.Eagerly,
            null
        )

On emulator or my Samsung S24 it acts normally. After sign in flow logs my logged in userId. After app relaunch same thing happens as expected.

But not on my Pixel 10 Pro... this one, behaves like it is not caching user data after signing in. Flow logs userid after I log in there and this doesn't change until app is alive. After relaunch tho it acts like the user never signed in and userFlow emits null

Devices OS:

• Pixel is running Android 16.
• Emulator is running Android 16
• S24 is running Android 15.

Same problem. Works on the emulator, but on my Pixel 9 Pro (Android 16) it clear the user when the app relaunches.
