Hi there!
I implemented an IAP Plugin due to documentation (added screenshots below), linked all consumable items to AppStore. After this i exported my project to Xcode and make a build. Here is the difficulties.
While i push the button "Purchase", it outcomes an unsuccessful purchase. There are some warning (added screenshots below). Need i to fix them or there are another problems ?
Maybe someone faced it before and can answer.
Thank you
