I have a great question..
If my Build Settings only have at Deployment info -> Devices -> Ipad.
Why i need upload iphone Screentshot and Previews for iPhone?
How to remove this step or maybe missing configuration at Xcode files?
How only upload iPad preview and screenshots at App Store Connect
Who said you need iphone screenshots?
Was that app set as iphone or universal at one time?
Which version Xcode?
What size screenshots did you upload so far?
