We are adding an feature in the app and we want to sell a special subscription for the app which lets users use the feature.
We might want to stop supporting this feature and remove it from the app in the future. Not just stop selling the subscription, but completely get rid of the feature in future version of the app.
Once the feature is removed, the users who bought the special subscription, will not be able to access the feature and they will receive the same experience as users who bough a normal subscript we are currently offering.
What is the best approach to deal with this situation?
Is it possible to force cancelation of this product or changing auto renew to off for all users who are subscribed to it?
Is it possible to force downgrade/upgrade of that product for all users who are subscribed to it?
Are we stuck with supporting this feature forever, or is there a best practice which will allow us to phase it out?
