All my Zigbee devices are now disconnected (22 Oct 2022)

I still don’t fully understand what is going on with these Smartthings changes. My zwave devices are all still working fine, but this week all my Zigbee devices are all offline.

I"ve tried all the normal things of unplugging the hub and plugging back in after awhile, removing batteries from my zigbee devices etc and nothing seems to work.

do all these devices need to be deleted and re-added? i’m mostly concerned about all my Ikea blinds

If you have a V3 hub and it’s been updated to support thread in the firmware update which is rolling out now, see the following for one possible cause:

Otherwise, you may need to contact support.
