I really hope they bring this back. The other thing I find really frustrating is not being able to spotlight search from within an app and initiate multitasking that way.
I really don’t understand why this was removed (or not fixed if it is a bug). Please keep providing feedback to Apple. It doesn’t make sense, iPadOS is suppose to make the iPad even more multitasking friendly.
In iOS 11 swiping up took you to multitasking app window but with iOS 12 and 13 it takes you straight to homescreen, so this gives even more reason to use drag & drop from the homescreen.
I didnt know you could do it with spotlight! My eyes have been opened.
