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,, and you most probably will have to tune your wifi and zigbee channels if you didn’t already
