For the last couple months when trying to power on or off, and once on, attempting to dim, my KL120 bulb is delayed in responding. Anywhere from about 5 seconds to 20 seconds. I often have to go and pull down to refreshing the listing of devices to get it to active.

I have deleted and added the device a couple times. I have reset the bulb to factory settings and reinstalled but the results are the same. The firmware is up to date, according to the app and there are no current updates for the app, as of February 6, 2023. 

If this happened to you and you found a solution, please share your fix. This is a nuisance. Thanks!
