Unfortunately, entering my real apple ID/password does not work. It show success but the upgrade/downgrade never occurs the UI still shows the original subscription level.
Signing out of the production AppleID and only having the sandbox tester on the device doesn't work either. In that scenario the password box is displayed but with an empty username in the dialog, entering the sandbox password just fails.
I'm confused how people are successfully testing these scenarios :/
