Related: I am going through Google's OAuth verification for a simple "sign up with google" function plus a non-restricted scope access. They say that the application is approved, the console has a green check mark and says "published" and I got an email saying that the application has been approved.

However, whenever a user actually tries to sign up, it says that the app is not verified. So I can't submit anything for review, because everything has been reviewed and approved, but it still doesn't work.
