I need to integrate in-app purchases with my existing web subscription option. Currently a user (email@example.com) can have an unlimited number of subscriptions, as they need a subscription for each team they manage. Does Apple's in-app subscription service support this? I can't seem to find anything other than their "Subscription Groups", but I would not want to create a group for every user/team. There are thousands of teams.
Any suggestions on where I should research next?
Use a single non-renewing subscription rather than an autorenewable subscription.
One user can purchase multiple non-renewing subscriptions.
