It's stupid that they changed the easy gesture we used to be able to do for pop-up view. It's way too much to have to go to recent apps and then take the icon and then search for the pop-up viewv buttonb and then tap it. And not only that but all Samsung apps don't work in pop-up view anymore. It's the most ridiculous thing in the world because they're the ones that created it, all Android apps work fine in pop-up view, but when I try to open any Samsung app in pop-up view it ends up going to full screen. For some reason it won't work. I also have the phone settings to be answered in pop-up so doesn't open the phone app every time I get a phone call, taking me away from when I'm working on. I can easily talk on the phone without needing this phone app open. If I need to access the keypad while I'm on the phone all I got to do is click the pop-up. Well Samsung pop-ups just don't work anymore. The problem is every freaking time Android makes a new OS, like KitKat to nougat or 8.0 to 9.0 & now 10.0, they f*** everything up that has to do with Samsung, & actually they ruin lots of apps' features. I can't tell you how many apps I have were there's a feature in the settings & underneath it says "If you have Android 8.0+ this will not work anymore." Android didn't used to do that until the last 2yrs or the last 2-3 OS's. And I bet you Samsung is a sick of catering their tech to Android's *****.
