I have a KL400L5, but it does not show on the dropdown list!

The website for the KL400L5 has shown "music synicng" now for two+ years.  When will this feature be implemented?

Sync to Music

Let your home audio shine as the light strip syncs to the frequency and beats of your playlist.

Note: This feature will release later in 2021.
