Have any of you used in app subscription and can provide some help on how to maintain them?
So far we've only used regular IAP (consumable and non-consumable), which are fairly easy to control.
however, to our understanding, we need to maintain and validate a user's subscription on the app every time he/she opens it. that means that we need to track the start of the subscription and inform the user when it near its end. we also need to take care somehow for multiple devices using the same apple Id, handle restore scenario etc. we see a lot of potential pitfalls that regular IAP don't have.
Would really appreciate if someone who used this can give us some tips.
