I know this seems like an obvious question, but I didn't manage to find any adequate answers for it in the net.
My problem: When the game is run on my iPhone 7, there are black borders around the game screen.
Solution found on the net: Change your splash screen to one that has the same resolution as your iPhone 7
Question: How to change my splash screen in a Monogame 3.4, 3.5 or 3.6 IOS project? (I have Visual studio 2017)
