I've been seeing some weird numbers on my Sales/Trend reports. Take this one from yesterday, for example. My application was on sale the entire day for $0.99 - the entire day. I made no changes to it's price at all. I checked a few times during the day to make sure it was showing up in the App Store as $0.99 both on my iPhone and also through iTunes. Yet, today, when I look at yesterday's daily Sales/Trend report, this is what I see: How is it that I have 16 units "sold" with a royalty price of 0? It makes no sense. Oh, and the "Product Type Identifier" column - both 1 and 7 are the same product. I only have one product on the App Store - again, what is going on? Apple did approve an upgrade of my app yesterday and that started showing up in the App Store, but I'd be surprised if that resulted in a different Product Type Identifier. I'm pretty confused. I've seen this before in earlier daily Sales/Trend reports - and, imagine this - my emails to Apple went unanswered. Has anyone else seen this? Am I just worrying about nothing, or am I really losing out on money? If so, is there anything I can do about it? Since Apple appears to be in a communication black hole, I'm worried that there isn't.
