SO I love the split screen but I think Im using it wrong...let me explain When I start an app and then want to start another one on the left hand side of the screen, I start the app, go back to the original app ( the app I want on the right hand side of the screen ) and then swipe from right to left to reveal the running apps. THen I select the app I want on the left side screen and drag it there.....SUCCESS. THe problem is that sometime the apps not there! I think it has to do with if I started the app in desktop mode or from the Modern interface. Is there a steadfast rule on how to get the split screen working everytime no matter where I star and app from?
