We are currently using an in-app purchase of type "Auto-Renewable Subscription", with an introductory offer of "Free" for two weeks. We haven't set an end date for the offer. (It's shown as "No End Date".)
At the moment, as we're planning to change the duration to one week, we're going to create a new introductory offer of one week and set an end date for the previous offer.
Our question here is, what happens to users who started the introduction period right before the end date that is newly set for the offer.
For example, if users start the two weeks trial period on the day before the end date, will they be able to use it for two weeks? Or the trial period finishes at the end date?
I couldn't find any descriptions about this in documentations from Apple.
Thank you in advance for your help!
Subscribers will receive the offer available at the time of purchase. So existing subscribers will keep their 2-week trial while new subscribers would receive your 1-week offer when they subscribe.
At a given point only one introductory offer period is active when you will create a new introductory offer period the start date of the new introductory offer period will become an end date of the previous and this should be reflected in your app store connect with the current Introductory offer and upcoming changes.
Please ensure you are following the best practice and using SKProduct to merchandise introductory offers accurately. Please refer Implementing Introductory Offers in Your App Display the Introductory Offer Section: Display the Introductory Offer
