No white light on my yeelight strips x2

No white light for my yeelight rgb strips that I just brought. How disappointing. My ID is 6150332636. Is there anyway this can be fixed? I’ve tried updating the software but no joy.

I have exactly same issue. I can only choose colour, but there are no option for white / light with no color.
This is something that should be mentioned in product description and on product package itself.
Very dissapointed. It seems the only real solution here is to return Yeelight to store and replace them with some other brand.
