We're trying to use PlayFabClientAPI.GetAccountInfo() to determine if an account is already taken. This works fine if an account is created using the same title, but if the account is created in a different title under the same studio this call return's an "Account not found" error.
Scenario 1
In Title A Create an account for example@gmail.com
In Title A Attempt to create an account again for example@gmail.com
Call to GetAccountInfo() for example@gmail.com returns an existing account
Scenario 2
In Title A Create an account for example@gmail.com
In Title B Attempt to create an account again for example@gmail.com
Call to GetAccountInfo() for example@gmail.com returns account not found
In Title B Finish account creation, call to AddUsernamePassword() with email = example@gmail.com return account already taken
Is there a different way we can determine if an email is already taken for the master account?
