Users complain that Xiaomi dark mode breaks the appearance in many apps.
(it arbitrarily inverts colors, even in their apps, contrary to Android guidelines)
Force dark mode usually exists in the (hidden) developer settings in other devices.
Xiaomi made it public in latest MIUI versions, breaking Android apps appearance.
Solution:
"Go to Android “Settings | Display | Dark mode | Individual apps” and turn off the apps,
you don’t want to force dark mode."
