Alfred 4.0.6 Build 1124, Friday 8th November 2019
MacOS Catalina 10.15.1 (19B2106)
If I attempt to switch to a fullscreen app from a windowed app or go from a fullcreen app to a windowed app the newly selected app is shown but it does not have focus.
If I switch from one windowed app to another windowed app then all is fine.
Any ideas ?
