CONFIGURED CLIENT IDS:

DESCRIPTION OF THE ISSUE:
When installing the app via the Google Play Store (Internal Testing track) on a physical device (Android 16 / SM-S721B) and triggering the native Google Sign-In authentication flow, Google Play Services immediately aborts the request, returning:

[ERROR] [GOOGLE_AUTH_NATIVE] Google Play Services Error: Something went wrong
→ Error Code: 10 (CommonStatusCodes.DEVELOPER_ERROR)

All SHA-1 and SHA-256 keys from the Google Play Console are registered in Firebase, the updated google-services.json file has been embedded in the package, strings.xml contains the correct server_client_id, and MainActivity.java registers the GoogleAuth.class plugin.

We request an audit of the Google Identity / OAuth 2.0 Client backend to check for any OAuth consent incompatibility or certificate propagation issues linked to project 816272065146.
