Cannot show all colors. Only Blue and Red!

I am having a problem with my Yeelight Bedside Lamp. It cannot produce any other color except red and blue! Can anybody confirm is this a software problem or firmware?

My lamp is in a good condition and I have never spilled liquid onto it. I havr had the lamp for almost a year. It is weird that the led cannot produce the other colors. Please help.

I tried changing the colors thru the lamp and the app but all doesnt work.

I am having the same problem.
When I turn it on it flashes blue and red colour.
Then through the app all the color options end up showing red or blue light.
White is ok but even in white color bar the yellow option is producing red color.
I tried multiple resets, no firmware update available…
