Multiple screen function disappears after auto sw update

[Android Central Question]

Samsung software updates ran last night (March 2, 2019). After completion, I no longer have the multiple screen function. Have checked settings, advanced features.... but found none. See attached screen shots. Please help.

You can't post screen shots here unless you register an account.

Are you talking about multiple home screens or running more than one app on the screen at a time? (You'll have to register an account to answer here too, or you'll be starting a new thread. And if you include @Rukbat in your post, I'll get an email that you answered.)
