New in HyperOS 2.0
on my Xiaomi 13 Ultra, when device is in Dark Mode
the navigation button bar at bottom does not comply to dark mode within a WhatsApp conversation. It is fine everywhere else including the conversation list within WhatsApp.
If dark mode buttons stay white, like in Spotify premium, update the app, clear the cache, restart your device, or toggle dark mode. Reinstall the app or report it if the issue persists.
