As some honest feedback..
I bought Construct 2 because it said I could create apps and monetize them on IOS, Android and Windows Universal apps.
I have been able to create a great game using Construct 2, as promised, but only a few feet from the finish line, very basic IAP doesn't work. Hundreds of hours of learning and development, with a significantly frustrating ending.
It does not matter to me whose problem it is. I bought Construct 2 to get to a promised end result that was promised by Scirra. I have no inclination to go to an annual Construct 3 subscription based on my experience with Construct 2.
If there are 3rd party issues, then create detailed troubleshooting guides to help us get across the finish line. I will keep trying to get my current version running. However, for the next version, I have already downloaded Unity and will invest the time in learning it. Yes, it will be a longer learning curve, but I can be assured I will reach the goal there that I couldn't here.
This could have been a great experience, but 99% of the way isn't good enough since it still equals a 0% result.
