Multitasking on Note 4 stopped working?

[jackjoe1234]

Hello, normally on the Note 4 you hold the back button for a few seconds and the mutlitasking side bar appears. Now it doesn't appear no matter how long I hold it. Anyone know why?

did it disappear after an update?

Oh. The multiwindow. Check if you inadvertently turned it off.
