Problem
We are implementing an auto-renewing subscription using StoreKit 2 to allow users to unlock Pro features in our application. Prior to this, our users would purchase a non-renewing subscription of 1-year access to Pro features, and would manually renew each year.
We want to offer a 2-week free trial to new customers, but exclude the 2-week free trial from users who have already had access to Pro features within the last 3 months (i.e. loyal customers who have been paying for Pro for several years).
Introductory Offer
Our current plan is to use an Introductory Offer, but as far as we understand this will apply the free trial to any user whose Apple ID has not yet purchased this auto-renewing subscription within the app (which would be 100% of our users), and we cannot define a user's eligibility for an Introductory Offer on our own.
Are we mistaken here?/Will users who have purchased a non-renewing subscription still be eligible for the Introductory Offer on the auto-renewing subscription?
Promotional Offer
We would like to use a Promotional Offer to apply the free trial at our discretion. However, we noticed the following stated under Promotional Offer in the documentation:
"Customers who have not subscribed within the app cannot complete this type of offer"
Does this mean that we will need to offer the free trial to 100% of our users?
Alternatives
Another option we are considering would be creating a separate Subscription product within the same Subscription Group that does not include an Introductory Offer. We would allow new customers to purchase the product with the free trial, and only allow existing customers to purchase the product w/o a free trial. We would like to avoid having to maintain multiple Subscription products for what is ultimately the same "product", and worry that this would be a misuse of Subscription Groups. Interested to hear if anyone else has done that, and whether that is allowed by Apple's app review.
