Hello,I am also facing the same issue here. Since last so many days sandbox environment behaving abnormally. We have submitted binary two times on AppStore with In-App purchases but unfortunately both the times they have rejected with some reason that purchase is going indefinitely when click on buy button. When I download same binary through TestFlight app and tested on our end, It works completely fine. How could this double behaviour of any In-App purchase in sandbox? Can anyone help me out here?
