While working on the auth block of my app, I've tried to sign-in with Google on a particular platform and the webview seems to get stuck after the credentials are submitted. I don't see a blank screen, it just keeps loading forever. Testing url: https://www.unrealengine.com/id/login?lang=en-US&redirect_uri=https://localhost/launcher/authorized/en-US&client_id=34a02cf8f4414e29b15921876da36f9a Works on Chrome, Vivaldi, Brave and Firefox. Doens't work on my webkit implementation and Epiphany browser. Steps to reproduce: 1. Launch the url above on Epiphany. 2. Click on the Google Sign-In button. 3. Enter credentials as usual using an account that has 2FA set.
