Awesome, thanks for clearing these things up for me!
Also, can I make a recommendation? It’d be awesome to have some kind of video tutorial that talks you through coded IAP and how/why it all works. It could just be a walk-through of the example project found here: Sample IAP Project
There is some stuff out there on yt for IAP, but it’s all codeless (which I have been informed is no longer being updated and will most likely be dropped in future updates).
