The smart bulb's unstable function

Hello! I have a Homey Pro, IKEA’s smart bulbs, and the “TRÅDFR” app. Sometimes they work as planned, next time they don’t, then 3 min later they work and sometimes they never start working again (until you reset). Anyone with the same experience and even maybe a solution? Is it Homey, IKEA, or the app that malfunctions?

Probably none in specific.
First inform yourself on how zigbee works, https://support.homey.app, and you most probably will have to tune your wifi and zigbee channels if you didn’t already
