2. Enroll a second factor by calling following method
   

   flutterfire/packages/firebase_auth/firebase_auth/lib/src/multi_factor.dart

   Lines 19 to 24 in 7132d77

   	Future<void> enroll(
   	MultiFactorAssertionPlatform assertion, {
   	String? displayName,
   	}) async {
   	return _delegate.enroll(assertion, displayName: displayName);
   	}

3. After you sign in again, enrollmentTimestamp returns 0.0

Thanks for the report. I do see same behavior on Android.

[Lyokone]

Hello, looking at the data from Android, it seems that the underlying SDK is returning 0.
I'll raise an issue in the Android Firebase repo

[htsuruo]

I added in Android to PR title, because it seems that the bug occurs only in android refer to #9363

Thanks.
