In my case, i had to register on a mac, not on windows. This reply will also test whether I'm only able to REPLY on mac rather than windows as well. If that's the case, I'm going to be pretty mad, because that's epic stupid. Why would the developer forums ( a website) be device locked? And why wouldn't they say so on the page?

Does anyone else do this process using the API? Apple just directly replied via email saying they don't provide support for their own APIs.

When I try endpoint 1 and I filter down to USA, I still get 95 price points, which is all the price points in the USA territory. The IAP item in question only shows one price schedule on ASC, Tier 5 / $4.99. How do I get the actual price of the IAP item, instead of all the possible prices I could set the item to?

I'm now polling all 16625 price points for ~300 IAP items each time I run my code, and I still can't find a way to associate an IAP Item ID with a Price Point ID. Any ideas?
