问题
I have following the steps described in this link to perform a sandbox testing. But I was failed to use the sandbox tester that I have created in iTunesConnect. When I tried to login using the tester account in App Store on an iPhone, it prompts the following error. I have verified the apple ID but it still failed. How to resolve it? By the way, is it possible to add a test card to a real apple ID for testing?

The Apple Pay Sandbox account is not for signing into iTunes, but to iCloud.

Important: If you mistakenly use a sandbox tester account to sign in to a production environment, like iTunes, on your test device instead of your test environment, the sandbox account becomes invalid and can’t be used again. If this happens, create a new sandbox tester account with a new email address.
