We offer a premium subscription and want to offer a 7-day free trial for users. However, we want to limit the amount of content they access on the free trial. This we can implement fine.
However, what if we have users who want full access and want to pay before the 7 days end? Do they have to “cancel” their free-trial and then subscribe again in the iOS settings? Or can they upgrade directly somehow to the paid subscription, before their free trial ends?
