Yeelight Ceiling Light malfunctioning after update


After updating my Ceiling Lamp via Yeelight app to firmware 1.5.9_0189 I’ve noticed a really bad bug.

Using the light in Sun mode, results in a completely dead warm leds. Meaning that in sun mode only cold leds work. If I try to change white temperature, shifting from cold to warm, instead of changing all the leds the light only dims the cold ones without turning into the warm ones.

The warm leds only work in night mode. This is a really bad and frustrating behavior.

Has anyone else faced this problem? If so, did you find any solution?

Thank you in advance for any help given!
Have a nice day!
