In iTunesConnect I have a 'Sandbox Tester' account that I use to test my iOS apps with.
Now I want to use this account to test IAP in tvOS.
When I add this account using tvOS settings, I get the message:
No iTunes Store Account
Before using this Apple ID on your Apple TV, you must first login into an iOS device, Mac, or PC to create an iTunes Store Account.
This account has been used before on iOS testing, so I don't understand why it tells me this.
How do I test tvOS IAP?
Thanks,
Bram
