LED Bulb 1S Color does not synced status with Google Home

Hi there,

I have 9 LED Bulb 1S Colors integrated with Google Home/Assistant properly. However, recently, their status (of being on/off/colorchange/brightness) doesn’t seem to show on Google Home App.

It only appears as off all the time (work okay via Google Assistant voice command though), even when I turned them on successfully via Assistant, it takes like less than 10 mins to show as off again in Google Home. (sometimes, even gone offline - not responding).

I also find them a liitle slow in Yeelight App itself as well

This is bad experience please help, let me know if you need more info.
