In the production version of the app, when I used the switch application button on my MX Master 3 mouse, all my open apps would be displayed and I could take my time to find what I needed. With the beta version, the apps appear but only for a couple of seconds and then disappear again, I barely have time to look through the windows to pick the one that I need (I need to click over and over again just to be able to get enough time to select).
