I believe the price confirmation is an automated reply because I've received the exact same message multiple times.

A friend of mine, an apple employee, requested I make him an app. I did, and Apple rejected it as a spam copycat. You cannot write comedy this good.

I have advertising ready to run on Halloween this weekend and not getting approved after hanging for four days will very likely cause me to miss out on sales I could have otherwise made. I don't understand how Apple can have a market cap of 5.09 trillion and still not manage to fully staff App Review. If we're going to pay money for a membership on top of a 15-30% potential cut of the profits, I think it is perfectly fair and reasonable to expect Apple to review 100% of all submissions (barring legal or safety reviews) within 48 hours with no exception and it's equally fair to criticize them when they fall short, which is often.

It doesn't matter if it matches the API or not, it is an incorrect pluralization of "collections". You can match the SDK api to the Apple Music API all you want, that doesn't change the fact that the underlying api design is incorrect and therefore, not working as expected.
