Hey. I would like to offer non-consumable in-app purchases in my IOS app and was wondering if I have to offer a money-back guarantee for non-consumable in-app purchases? So if someone buys my app, can they return it? Or is that generally not possible with non-consumable in-app purchases? If there is no money-back guarantee, do I have to point this out to the users? In addition, I was wondering if there are bugs in my app that I didn't know about, do I have to give all my buyers their money back? Because I then sold a defective product... I would be happy to get a answer.
