You have it everywhere else... Why not here?

Subject: One Drive App
My suggestion is that dark/night mode should be enabled in One Drive. The option should,
1. Provide user to set the specific time say 7 pm to 7am next day.
2 the option should not depend on the device except that it may be a smart phone. In fact, Wikipedia provides a kind of dark option thar in features its app itself. But it doesn’t provide timing option.
