Most families have a single parent account that is logged into the itunes store and the persons personal account is logged in as the main itunes account for the device.
This means that my account is used for my main game account and also as the store account for me, my wife and kids, all of whom play magic.
When I subscribed, the subscription also turned up on my wifes phone even though she got none of the items saved to her account and she can’t subscribe herself, the option is gone.
This annoying, but the bigger problems are potentially in the future… This implies that my 2 kids accounts are currently subscribed too, so what happens next week and then next month?
Do all 4 of the connected game accounts that claim to be subscribed get the rewards? Or is the system going to have a serious barf because it’s expecting a 1 to 1 mapping between account and itunes id, but it’s using store id instead?
I suspect this is currently ticking time bomb that has small immediate issues but is about to get much worse!
