I need my app to not use iPhone 6 Plus' native resolution and rather scale up from iPhone 5/6.
I have removed the Launch Screen File and cleared "Retina HD 5.5" from the Launch Image, yet when people run it on iPhone 6 Plus, the app is still using its native resolution. Note that removing the "Retina HD 5.5" was sufficient to bypass iTunesConnect App Screenshots validation for iPhone 6 Plus, yet the app itself is not honoring that.
Is there anything else to remove to eliminate iPhone 6 Plus native resolution?
