No available windows
When I try to open mission control from launch pad, there is a message on the center of the home screen that says no available windows. I find no reference to this message in any manual I have read.
MacBook Pro 16″, macOS 10.15
The message is indicating that whatever the active app is (look in the menu bar), there are no open windows in it. For example, you close all the windows of MS Word but don’t quit the app.
