Function signInWithVerificationId only link to the current user on Android

[JulesLagadic]

I try to link the phone number to an existing user account. Everything works perfectly (SMS code received, verificationId received) but the function signInWithVerificationId seems to be different on iOS and Android :

• On Android, if there is a current user, the user is updated with the phone number otherwise a new user is created
• On iOS, a new user is always created, even if there is already a user connected

Is it possible to add the same condition on iOS than Android to get a consistent behavior ?
