4.0.1

Bugs Fixed

• Fixed an issue that prevented the login function from working correctly with Sign in with Apple and anonymous account. This was caused by the fact that the Firebase error returned for these cases is different: please note that SIWA credentials are not reusable, so if a user is signing into an account that already exists while being logged-in as anonymous, they will have to sign in twice. This process is handled entirely by RxFireAuth.
