🐛 [firebase_auth] sendSignInLinkToEmail not working on iOS

[MATTYGILO]

Bug report

when I run sendSignInLinkToEmail on iOS it does not send the email to the users email. However, this works on Android.

The only time this works on iOS is for an email that has been previously tested and set an email from android.

Steps to reproduce

1.Create the app on iOS 2.Use an email that has not yet been sent a sign in link 3.sendSignInLinkToEmail

It doesn't work

Expected behavior

An email should be sent to the email with the signin link
