LED Light Strip 1s no white colour problem

Hello Yeelight. My Mi ID is 6505883783 and i am facing a problem with my new smart LED Light Strip 1s. My LED Strip hash not have white colours as a choice intergrated like my Smart LED Bulbs 1s has. All lights had been updated to the latest firmware version such as the app. I am using Yeelight App and my server is EU Germany. I’m looking forward to your reply.

Hello, lamp belt 1S itself does not support white light.
