I have 4 tiers: NoAds, Pro, Pro+ and Platinum. Each tier has monthly and annual.
As I understand, on AppStore I have to create one subscription group. So there will be 4 service levels and 8 products in total which will be put in descending order.
Question: If a user uses the introductory offer for NoAds but I want to offer them introductory offer when Pro launches, how do I offer it to them as only one intro offer per group is allowed. I can’t move NoAds and Pro (and others) in separate groups because NoAds is a subset of Pro and hence at one time only 1 tier can be active. This is pretty straight forward in Android as every tier can have its own intro offer but Apple is tricky.
How do I manage it?
