I used to be able to arrange the home screens ( pages ) in iTunes prior to iOS 11. I could create new empty pages, ect.
Is there a way to do this? For instance switch homescreen #2 for homescreen #3?
Depending on your setup, you have two options.
Apple Configurator 2 provides much more advanced features in terms of managing your iOS devices. However, if you don't already have it installed, then the current version (v2.5) requires macOS Sierra 10.12.5 or later to run.
