Sunrise/sunset feature for Yeelight White bulb is online

For Yeelight White bulb users who are asking for Sunrise and Sunset feature, you can now use it in Yeelight app or through IFTTT.
The applet is here:

Please select your white bulb in device field and select “sunrise” in the lights field.

This is not working for me. The white bulbs are not gradually getting dimmer after triggering this though the yeelight app or ifttt.

Can we have a Sunrise and Sunset schedule added to all lighting in the app?
