Yeelight Colour flickering after power outage

Hello, it was very windy this morning and the power went out for just a few seconds. My two white bulbs turned on just fine after the outage but my two E27 colour bulbs are flickering like a strobe light. The Yeelight app said the bulbs were offline and I was unable to reset the bulbs. I attempted a reset but it just keeps flickering and sometimes after turning it back on, it will flicker for a second, then cycle through all the colours and then resume flickering.

The two colour bulbs were very troublesome to set up when I first got them but I hadn’t had any problems since. What can I do?

What’s your power voltage? 110v or 220v? And also the frequency of your AC?
