AuthorizationAppleID(001745.849ed9d3f6414afabfa47794178d1a4f.1018, null, null, null, example-state).

This is working as designed (by Apple). Subsequent "logins" (after the initial registration) return null for givenName, familyName, and email.

[Sayedmdkaif]

in the next login how it will work?

[HenriBeck]

@Sayedmdkaif you need to save these details on your server

[Sayedmdkaif]

after saving detail how to login next time?

[HenriBeck]

I would suggest reading into the topic on Apples Developer web or using Firebase to handle such things for you

are you sure this problem not come by using firebase?

As said, this is by Apple's design to only return name & email on the initial sign up (also see the various questions about this here in the issue tracker). There is nothing the plugin can do here to help you there. It's the implementors responsibility to save that data somewhere if they want to retrieve it later (by the user account ID, which is always given in the AuthorizationAppleID class).

I don't see anything Firebase-related in the issue described, this will behave the same way no matter what backend you use.

Whether or not Firebase does support storing name & email and thus could help you in retrieving that data later on I don't know. All implementations I have seen use a in-house backend implementation.
