Problems with the lighting

The brightness changes after the end of the current animation cycle. Wait a few seconds.

Turn on night light mode. Take a close look at the light. If you find any dark dots, contact the service center. If the glow is even and everything is fine, it's just a feature of the animation.

There are quite a few sound parameters that define the light animation during audio playback. Try playing a different track. If the problem persists, contact support.
