Notes:
- The demo project attached is a Google OAuth example
- Thread about this issue with a suggested workaround in Unity forums: [https://forum.unity.com/threads/deep-linking-in-unity-2022-the-app-is-restarted.1447300/]
- Does not reproduce in Play Mode
- Does not reproduce on Windows Standalone Player
- The issue itself is not specific to deep linking. The activity attributes are not being added to the AndroidManifest when generating it, {color:#00875A}{{android:launchMode="singleTask"}}{color} is needed for deep-linking to work properly.
