I tested a subscription with my developer account, it never charges but at the same time I can't cancel it anymore. It does not appear in the list of my official purchsed subscriptions. I tried to login to the sandbox with my developer account, but then when I click on "Manage" I just keep getting the error "Can't connect - retry". I have already tried to logout from all the services, App store, etc. and re-login, nothing worked. Is there anything I can do? Thanks in advance to anyone who can give any tips.
