iOS 11 iPad Dock last used apps

Hi @all,

I have iOS 11 on my iPad and tested the last used apps in the dock.

As the apps were shown in the last used area, I touched one of them, the same way, if I want to delete an app.

The apps and the last used area were shown with a minus. Clicking the minus sign removed the app from the last used area. In my case, Safari.

Is there anyway to bring a back?

Because since this time handover for Safari doesn’t work anymore for my iPad and iPhone.

Thanks in advance for your tips
