I built my Android app with Lovable and have it live in a closed test on Google Play. • Google authentication fails with a "Google sign-in failed: [16] Account reauth failed" 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. What I expect from you 1. Diagnose and resolve the Google Sign-In 404 so that login works on all current Android versions. My technical skills are somewhat limited so I need your patience :) We can work through a quick TestTrack update so I can verify both fixes before we push to production.
