Unable to use Galaxy S8 screen edge on games

[AC Question]

I am having problems with being able to use the edges of the screen. With some of my games, they have buttons that are on the top and the bottom of the screen while in a horizontal position. I have to get as close to the flat part of the screen as I can and that can be hard if they are small buttons on the screen. I am unable to use the edges when I have any apps open. I don't want to extra edge settings on, so I have those off. I didn't have this problem on my S7 Edge and the settings are the same.
