Yeelight Bedside D2 Keeps disconnecting from Homekit

I recently bought the Yeelight Bedside D2.
I connects well to Yeelight App & HomeKit App.
But after 5 - 15 mins of use, it’s just disconnecting from all the apps.
Do you know this issue?

Hi You can delete the fixture and re-add it, make sure to update the fixture firmware to the latest version

Of course, I did it several times
It’s still makes the same problem

yes me too and also other yeeligght are offen disconnected
