Ceiling light couldn't be found by Alexa

The light turned on, both ceiling light and Alexa are connected to same wifi network, I downloaded the Yeelight skill to Alexa but it doesn’t appear

You need to connect your lights to Singapore or US server to make it being able to discovered by Alexa.

I changed the server to Singapore. I can control the light from the Alexa skill but when I ask Alexa to turn on/off alexa can’t find the light

I am experiencing the same issue please fix

Do you mean you can see it in the Alexa app but can’t control it through voice?
