dark mode disabled after upgrading to 3.4.2
I have been using version 3.4.1 which, without my doing anything special, was in Dark mode. (and yes Dark Mode is enabled in my Mac's system preferences)
Now, after upgrading to 3.4.2, the Dark mode is gone, and I don't see how to re-enable it.
I'm on MacOS Catalina (10.15.6)
Please someone let me know how to re-enable Dark Mode.
Note: I tried to completely uninstall/reinstall but no luck. Even tried to go back to 3.4.1 but the Dark mode is no longer enabled...
