When I build the application and open it on ipad pro, the resolution is low, as if regular ipad resolution was stretched out. I understand the concept of using launch storyboard to correct this issue, and I have employed that strategy in MM 3.4.2 and it worked fine.
Any ideas why it's not working on MM 3.5.2?
So, it appears that I was trying to build the app using the 'legacy' method of uploading a zip file to phonegap. After building the app using the command line, the resolution adapts as expected.
