I have Dark mode selected on the macOS app and when I fully close the app it shows light mode and in the selection it shows that dark mode is still set. If I close the app regularly on macOS the dark mode switch correctly saves and displays dark mode - which resets again once the app is restarted.
Found on macOS version 2.22.0 (1.28.0).
