This may seem like a stupid question, but I am very new to iPad and I am even more new to iOs 11. I know how to turn of an app in split view but I cannot turn off an app in slideover. I currently have gmail and Safari open, wich works like fine but I cannot find out how I close Safari without actually going to the app switcher and turning both apps off simultaniously. I am particularly new to this. I got my iPad right before iOs 11 and didn’t know how to do it in iOs 10 but didn’t actually learn how to do this, but I learned it in iOs 11. Now I can do most things except turning up an app in slideover. I think I am fine with other things.
