Android API 31 FLAG_IMMUTABLE Error using Firebase Auth UI - firebase-authentication

Question

I'm receving the below error in API 31 devices during Firebase Auth UI library(Only Phone number credential),
Fatal Exception: java.lang.IllegalArgumentException: com.sstech.racemanager: Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified when creating a PendingIntent.
Strongly consider using FLAG_IMMUTABLE, only use FLAG_MUTABLE if some functionality depends on the PendingIntent being mutable, e.g. if it needs to be used with inline replies or bubbles.

I've searched online and for some the issue is resolved by adding androidx.work:work-runtime-ktx:2.7.1 pacakage, but in my case even this is not solving.
Can anyone help on this issue.

Answer 1

In my case, firebase UI (com.firebaseui:firebase-ui-auth:8.0.0) was using com.google.android.gms:play-services-auth:19.0.0 which I found with the command './gradlew -q app:dependencyInsight --dependency play-services-auth --configuration debugCompileClasspath'
This version of the play services auth was causing the issue for me.
I added a separate
implementation 'com.google.android.gms:play-services-auth:20.0.1'
to my gradle and this issue disappeared.
