I have my iPad Pro (11-inch) on iPadOS 13 connected to my MacbookPro 15" running Catalina via the provided USB-C to USB-C cable but when trying to access Sidecar I get the following error:You can’t open the “Sidecar” preferences pane because it is not available to you at this time.To see this preferences pane, you may need to connect a device to your computer.Has anyone got this working yet?
