Background: I finished developing my first B4I app with my testing device of iPhone 5s, I then used the screenshot resizer tool to generate other screenshot sizes for my app and uploaded to the app store. I got Metadata rejected because the images on larger screens look stretched in width. According to Apple resolution centre, the images were not from the correct device frame.
Wish: If it can be possible, can we get various screenshots from the hosted builder or get a tool that can emulate the various devices and generate the right screenshot for those who do not have a local mac or various devices to capture the correct screenshot for the device sizes.
