When you currently publish your app to the appstore, your app is scaled up when using an iphone 6 or 6s. This can be fixed by manually adding the splash screens in the config.xml, i.e.
<gap:splash src="res/ios/Default-667h@2x.png" gap:platform="ios" width="750" height="1334" />
<gap:splash src="res/ios/Default-Portrait-736h@3x.png" gap:platform="ios" width="1242" height="2208" />
<gap:splash src="res/ios/Default-Landscape-736h@3x.png" gap:platform="ios" width="2208" height="1242" />
Is there a reason for the iphone 6 splash screens missing on the publish section on sprintr?
