I’m unable to activate dark mode on the Lumo Android app (running on Android 8/Nokia 8); the “Appearance” setting is missing. Even after enabling “Force dark mode” via Developer Options, the app stays bright and the input bar floats in the middle of the screen instead of anchoring to the bottom. It would be great if Lumo provided a functional dark‑mode toggle and proper UI layout for older Android versions, or at least offered a clear fallback/web‑app solution for those devices.
