Yeelight YLXD76YL ceiling light disappears in yeelight app and keeps saying "No response" in iOS HomeKit


I have purchased two Yeelight YLXD76YL ceiling lights. When I try to connect to them via Yeelight app for iOS, they connect, but disappear in couple of seconds after. I manage to connect from iOS HomeKit, but the most I could use it was a day. Then they become unresponsive (“No response”) and I have to connect them again.

What can I do to fix it?
