Safari (or Firefox) opens a pop-up that says "Would you like to allow this app to open Teamviewer" (or choose an application in Firefox), you click allow and the window goes away but nothing happens. Is there some funky security thing that's new in Big Sur? This all worked perfectly before the update.
