I have 9 KS220M switches in my house and they all updated at the same time and the app froze / Wi-Fi dropped part way through. They are no longer working for my needs (either due to the interruption or the new firmware) and I would like the firmware rolled back to 1.04 please. I have already tried restarting, hard resetting / adding, etc. I just need a support member to push the older firmware to my devices. Thank you!
