MacOS (big sur) cmd-tab lets me tab over to another app, correct? Well, it does, and it doesn't. It doesn't always bring up the UI of the next app, forcing me to bring up the dock and find it there and click on it which breaks my workflow. But sometimes it does bring up the UI? The inconsistency is confusing. What is that about? Is it a feature? Is there some option I can turn on that always brings up the UI of the app I'm switching over to?
