Seems that iPhone is not loading AngularJS right

Hi,
I have a strange problem with my Ionic app. In xcode simulator everything works fine, but on my physical device (iPhone 5s, iOs 9.3.3) ng-if and some other stuff doesn’t work. I attached a screenshot.

Does anybody have an idea?

Thanks,

Robert

I know this was like 5 years ago, but was there any resolution?
