The information is unclear and confusing. It needs step-by-step explanations for everything. This documentation is a nightmare. I think I'm going to throw out IAP and not make any money with this game after years of development because trying to do IAP is a nightmare. Wish you would do your developers a service and make IAP the easiest part to do so developers can MAKE MONEY. We are mostly making games TO MAKE MONEY and if we can't MAKE MONEY, why would we use Unity? Why would we pay Unity to use cloud services if were NOT MAKING MONEY? Why would we pay Apple $100 a year if we are NOT MAKING MONEY? The IAP and Ads should be the easiest part to do with the best, most thorough documentation, videos, tutorials, examples so that ANYBODY can do it, even programmers.
