    - Fixed the system theme: Lumo now correctly follows your device's light or dark mode, including at startup. - Fixed account switching: the app now opens on the account you have selected, instead of sometimes loading the last-used one. - Improved sign-in: after entering a second-factor code you now go to the correct password screen, and "Reset backup password" can be reached from the backup password and pending-approval screens.

    Lumo 2.0.3 focuses on a faster, smoother startup — the app launches quicker and loading, background, and keyboard animations no longer stutter. The loading and offline screens have been rebuilt as native screens, including a new connection-error screen with a Retry button that follows your light/dark theme. We've also polished the interface so the status and navigation bars match the app background.
