Hi! I work for a b2c app and we are getting current users complaining that when they use Sign In With Apple -> Hide Email -> this creates a brand new account for them and they complain all their data is lost. But that is because they used their regular email to sign up and not Sign In With Apple button that we have.
Then vice versa, users sign up with Sign Up With Apple -> Hide Email -> this creates an account fo them then later on they log out and log back in and try to login the regular way using their email and not use the Sign In With Apple button and then they complain their data is lost. This is creates two different accounts.
Is there any way to integrate both? So if a user did Sign Up With Apple and a hidden proxy email was created but then later want to sign in using their regular email (not using Sign In With Apple), we can detect only one account? Is it possible to detect the same account with the hidden proxy email even though they signed in with the regular email?
I hope this makes sense. This is making users mad because they don't know how they signed up. Any information is appreciated. Thank you!
