Wow, this is ridiculous. I would give zero stars if I could: I paid for the upgrade to the app, but never received the upgrade. I called Apple and they said I have to contact the developer. Ookaaay, but the page in the App Store has no way to contact the developer. Apple says they can’t contact the developer. Ummmm, you communicated with them when you received the app from the developer, right? You communicated with the developer when you negotiated price and terms, right? Or did the app just magically appear in the App Store? Since Apple manages purchases and upgrades directly with the consumer, shouldn’t there be a way for them to trigger the upgrade? Is it that they are too lazy to try to truly help the customer…Or maybe too cost conscious, or incompetent? Definitely not the business model upon which Apple was founded. It’s too bad because the basic app is quite good, but very limited.
