Yeelight Color 1S bulb very dim on white

Hello, my bulb (placed in an IKEA lamp) is very dim when I’m turning it on from the Yeelight app (in white color picker) and the more warm tones are straight-up red, but the RGB works perfectly fine. This behavior disappears if I “restart” the lamp (plugging it out and back in) a couple of times (usually two times). Any idea what this could be?
