Ceiling light A2001 doesn't appear in Homekit/App

Hello,
I have bought a ceiling light A2001, added it to homekit and yeelight app, but almost always shows as “offline”. So automation doesn’t work, voice control doesn’t work, customization also doesn’t work…
I can control it only with a remote, althought the lamp shows as “connected” on my router… Any chance to fix it? Otherwise, it’s no better than any regular “stupid” lamp…
Firmware: 2.0.6_0003
Router: Mikrotik RBD52G-5HacD2HnD

MI ID: 4185545318
I’d like to try the beta, 'cause it’s impossible to use the lamp through phone…
