I have the exact same problem.
Since I updated the firmware it’s not possible to enter the moon mode anymore. As soon as I want to adjust the brightness of the moonlight the lamp exits the moon mode .
another problem since the update is that if I use the remote to cycle throw all the colors of the ambilight by long pressing the sun icon I am not able to get bright full red color as it was possible before.
As I like the immersive full red color of the ambilight the most, it would be greater if this could e fixed.
Another issue is that if only the ambilight is turned on it’s not possible to turn of the lamp by single pressing the off button on the remote.
Even if I press the power button in the yeelight app the ambilight does not turn off. The app shows that the light is turned off but the ambilight is still on. I have to turn on the light again and then turn it off again to really turn it off completely.
Even Alexa can’t turn of the lamp if only the ambilight is on.
I have to first turn on the light with Alexa and the turn it off again . It would be great if this could be fixed .
A colorful flow mode as it’s possible with the e27 light bulbs would also be great. As it shows the real beauty of the lamp
