For around 9 months 1 of my 7 bulbs doesn’t work properly. I have updated firmware and reset many times.
It just fixes itself now and again and then breaks again.
Most of the time when it is working, it doesn’t have any light at all for white.
I have seen that it shows the wrong colour for warm white when it has no colour for cool white.
All other colours work though I don’t know if they might be slightly the wrong hue or anything.
It’s on the latest version, updated couple of days ago.
