Rob, fair point.
Perhaps the answer is to make it mandatory for each new IAP provider to write their own tutorial from a Corona SDK perspective. This would help relieve the workload on your part and also put the accountability back on the new service providers shoulders. If they want us to use their service they need to make it more accessible and understandable etc being the the logic.
How about a blog / tutorial for the Apple IAP though. Lets forget about all the others and get Apple right. Seems like a number of us are still stuck with a the basics. Thanks so much for considering this.
