Not sure if this is a known issue but I'm using v90 and latest version of MacOS. When I click and hold on the green split screen button for the device window, the OS shows the split screen that you want to drop it in. When I try to drag it to one of the sides it fails, but now it's stuck in this split screen mode and I can't seem to get out of it. I've had to hard reset my Mac every time. Any help with this?
