I had to make my size 390 x 844, but when I did this and turned on "Display Device," I couldn't see any changes (the iPhone frame doesn't appear). And this is even the same in the Preview mode. I am very worried about how it would look in a real app. Should I include an App bar? because this seems to solve this problem, or can I just leave it as it is now?
Edited: I have one Idea, which is to include an app bar. But I am thinking the height of 44. Would this be fine to avoid any intrusions.
