Has anyone successfully been able to use Sandbox Accounts with Apple Sign-in?
I have been trying to do this on the Watch, but I have "Two-Factor Authentication Required", and when I try and add this to a Sandbox Account I get "Cannot Set Up Two-Factor Authentication - Two-Factor authentication is not available for your Apple ID at this time."
It's possible that a server is down somewhere, and at a later time, I'll be able to set it up. But I suspect it's just a generic warning, and I cant set it up due to the type of account it is.
If anyone has had any experience here, I'd appreciate some advice.
Same problem for me still. I don't get it. Isn't it really common to have sandbox user to test Purchases ? Also Apple Sign-in is the first choice for signing in. How to people test their apps ? (It's already not possible fully on a simulator...)
