Mi Led Smart Bulb Stuck with Old Firmware

Hello, I have three Mi LED Smart Bulb Color, equivalent to Yeelight LED Color Bulb v2, which are stuck with firmware 2.0.6_0035. I know multiple subsequent firmwares were released but I did not get them neither from the Yeelight app nor from Mi Home.
I’m having lots of issues with HomeKit where the devices go offline after a couple of days.
How can I update the firmware to see if those issues were resolved?
