If I were to uncheck the "Cleared for Sale" Checkbox under my App Subscription, what would happen to users that are already subscribed and the new payment cycle arrives ex. if it was a monthly subscription?
In App Purchase Subscriptions
When you clear an in-app purchase from sale buys will not succeed example: new purchases, renewals, or billing recoveries. Ensure you are providing service to customers until their subscription expires date. Please refer to this guide for more information: https://help.apple.com/app-store-connect/#/dev360aba524 section: "Delete an in-app purchase"
