I have a Keyboard app for iOS that was rejected because it doesn't include the basic keyboard functionality.
The app is a sticker app that lets you copy and paste emojis. However, the app is required to have "both" alphabet and numeric keyboards as well. Currently without "full access" enabled in keyboard settings, the app doesn't function. When "Full access" is not enabled, the app should still have the alphanumeric keyboard.
I'll give a 10 rating for good work.
