I initially tried to implement IAP without code, but the flexibility was too limited, so I went back to a code-based implementation.

Then the callbacks were not firing, and I spent 8 hours debugging before realizing the issue was a simple toggle setting...

This is exactly why you should understand each step rather than blindly following tutorials.
