Apple told us that we need to send users outside app (close the app and open a Safari) to collect payment. I am worried that this is going to affect our user experience. Apparently, we can't have an embedded solution for payment. It has to be outside the app. Do you know of any good example for this?
Audible is like that for audio books (or at least it used to be -- I haven't bought a book from them lately). You had to go to Audible's web site to buy an audio book before you could listen to it in their app.
Are you certain they won’t let you open a web view within the app?
