I built my Android app with Lovable and have it live in a closed test on Google Play. Two issues appear: • Google authentication fails with a 404 error the moment a user tries to sign in. I need the sign-in flow to complete successfully, returning the user profile as expected—no error messages and no fallback to guest mode. • The wrong launcher icon is showing on devices and in the Play Store listing. I have the correct asset set, yet it is not the one that appears once the APK is installed. What I expect from you 1. Diagnose and resolve the Google Sign-In 404 so that login works on all current Android versions. 2. Ensure the correct high-resolution icon displays everywhere: home screen, recent apps, and Play Store. We can work through a quick TestTrack update so I can verify both fixes before we push to production.
