I submitted an update for my app in iTunes Connect which Apple rejected, giving the following reason:
We noticed that your app did not run at iPhone resolution when reviewed on iPad running iOS 10.3. Specifically, the screen resolution was not optimized for iPad.
But I set the app to only support iPhone in the Deployment Info, under 'Devices', so I do not understand why they would test on an iPad.
I tried looking to find out how to make sure iPad isn't supported, but I do not have a storyboard for iPad and I only uploaded iPhone screenshots to the App store. How can I fix this error?
