Hi, my Yelight color bulb used to work with both Alexa and Google Home. Then after switching on and off, it is "unresponsive" to both. I had to reconnect the bulb to the app, using the US server. Now it works with the app but not with Alexa or Google Home. I tried removing the device and the skill from Alexa, re-enabling the skill and re-discovering the device. Alexa can find the Yeelight Color Bulb but still says it is unresponsive.
