In-app dark mode is not enabled automatically

1

Hi, my phone model is Huawei Mate 9 and it has Android 9, the dark mode is not activated automatically based on the system settings on my phone, what should I do?

2

Set it manually?

Not sure “auto” dark mode works before Android 10

Hello, it is in follow system mode, I think it can be implemented in Android 9 as well , but the instructions are different.

depending how the vendor implemented system dark mode on 9, apps may or may not be able to detect/handle it

The developers of this app can modify the app to be compatible with how the automatic dark theme switch is activated based on the system settings in Android 9.
