ylsd01yl stopped working with Xiaomi Gateway 3

Some time ago my ylsd01yl spotlights stopped working with the Gateway 3. However, if I connect it to the Alarm Clock, it works. I suspect it’s a firmware issue, because the Yelight Downlight M2 got updated and works now. The current firmware version is 1.2.0_0063, and it says it’s the latest. Is there a way to update these spotlights to a newer version? My Mi account is 6688783721

It seems that nobody here really cares about the users problems. Can someone suggest where I can turn to have my spotlight fixed after protocol changings?
