UMG Fonts look pixelated in iPad Air

I have textfields in the UI that seem to render fine in PC and MAC but are pixelated in iPad. The DPI scaling is set to shortest side with 1536 set to 1.
Also I have r.ContentScaleFactor set to 2. But still the fonts don’t seem to look sharp at all. Is there anything else that needs to be done to make the text sharper.

I figured out that the resolution used was 1024 x 768 instead of 2048 x 1536. But I did set the contentscalefactor to 2 in device profiles for iPad Air. I ended up setting the contentScaleFactor in code since I am using the code version of the engine and it seems to work. Is the way we have to do this now , why does setting it in the device profile didn’t make any change ?
