Apple ejected my app for using Google Sign-In

Since we can't see the reject letter I assume what they rejected it for was not being able to access whatever you are going to google for.

When you submitted your app did you include the user id and password for google account?

Apple must be able to access any referenced URL and if they can't it will be rejected. What you have to do is provide a practice account for them to test it.

 

Um....first of all, Apple doesn't care if you use Google sign in.

I think you might have problems understanding what they're actually saying. It sounds to me like they rejected your app because of its association with the Pokemon franchise, probably without legal/copyright permissions.

I can't stand it when people come on here whining that Apple rejected their app without actually explaining the real reason.
