Hello, When I connect to my Mac using iPad, App Launcher seems okay at start. Then it disappears, and all I can get at the bottom of iPad screen is row of esc, tab, etc, over to set of 4 arrows. Swipe from right edge of screen does not get me to the App Launcher. Using latest of all s/w. How to get App Launcher back? THIS IS A SHOW STOPPER. Useless hassle dealing with it! Any fix known?
