In my reactjs project, I use firebase 9.6.11 for email, google and facebook authentication.
When I call the signInWithPopup() and google sign in form, Sign in to continue to show projectid.firebaseapp.com. I have already update Public-facing name at firebase's project setting.
Even though I have add custom domain, google sign in for redirect link also using projectid.firebaseapp.com url.
My project is hosting on firebase hosing and link with web app.
If anyone facing this issue, please follow the step in here Step to change custom domain
For me, I forgot to enter OAuth 2.0 Client IDs's redirect url
