I want to add in-app purchasing to my app, but I can't figure out what part of my workflow is wrong. I created a product for my app in iTunes Connect (the product ID is com.mycompany.products.***) and it's in "Ready to submit" status. I created a sandbox test user for this app. I connected to iTunes on a real device using the sandbox AppleID. I went back to XCode and added in-app purchasing to my app. I turned on developer mode on the real device and logged in as the sandbox user. I built the app and ran it on a real device (not the simulator). I tried to get product information (com.mycompany.products.***) but nothing was returned. In-app purchasing is registered in App Store Connect and the status is "Ready to submit". The code only retrieves product information in a simple way, so I don't think there's a problem. inAppPurchase.getProducts(["com.mycompany.products.***"]).then(console.log).catch(console.error); But it only returns an empty array. What could be wrong? Any help would be much appreciated.
