Hi! I want to change our in-app book to updated one. But how to do that correctly? What should I do first, second, third?
How to replace in-app purchase in my app?
As long as the product identifier is not changed between the old and new versions, users will not have to repurchase it. You should also add some code that reads the timestamp of the purchase, so that you will be able to tell if a user has the updated content or if the new one needs to be restored to the device.
That seems legit. Thank you.
Any other questions/concerns?
