I have set up and tested In-App purchases successfully in sandbox environment. But I have a problem:
In actual In-App purchases, I can turn off auto-renewing subscriptings on an iOS device by following this link http://support.apple.com/kb/HT4098?viewlocale=en_US&locale=en_US
I wonder how I can do the same thing in sandbox environment. I thought we have to sign in App Store to turn off auto-renewing subscriptings, but Test User Account can not sign in App Store. So I think we can not turn off auto-renewing subscriptings in sandbox environment.
If so, I also need a simple explanation why we can not.
Thanks for reading and any help or direction will be appreciated.
