When I change my tile colour to bright highlight and dark highlight it doesn’t change, but when I use the marker, the color changes. My device is a Redmi K20 pro. I just got the Blloc installed today.
@abhijaymk69 welcome to the community
Tile highlight dark and white works only if you have focus mode turned off or sun mode turned off.
So turn off the Focus mode.
This is not a bug.
