When creating a device profile that sets specific cvars for the ipad pro. They don't seem to be loaded or used in a launched game or in a packaged game.
While testing in 4.10 if I changed the IOS device profile (there is no ipad pro profile by default) to have cvar "r.MobileContentScaleFactor = .5" and then launched, it would successfully change resolution. This didn't work in 4.11 using the same steps and workflow.
RESULT
There is no change in the resolution and the cvar doesn't get applied
EXPECTED
The cvar gets applied and the resolution is very low causing the print string text to be very large.
