The theme keeps resetting randomly to "dark" - although it shows that the "light" theme is enabled - it still switches to "dark", i.e. the interface is the dark mode. I then have to Disable and Enable the Light Mode for it to be Light mode again. But, then even within a few minutes, while I might be doing something else - when I go to Thunderbird, it has switched to Dark mode again .... This is FRUSTRATING.
