Why will screen captures from the iPhone simulator not upload to the App Store Connect?
Why does Apple make ANYTHING Apple so flipping hard? Why do I need screen shots for a business only app?
Why won't screen shots from the simulator upload?
Why won't they upload? What happens? How are you uploading them, just dragging them onto the area on the web page? Are you getting any errors? What are they?
Can't really help you if you just rant and don't give us any information.
Just accept that you need screenshots for all apps.
