I had an extremely reliable Zigbee mesh that now seems to be much less reliable since the update. Zigbee logs did not seem to be capturing device activity accurately (far more sensors getting triggered than were logged). Outdoor lights (have 20 zigbee candelabra lights in five fixtures) are not responding to hub commands consistently either.
Prior to update, this did not happen -- so I suspect this is tied to the update. @bravenel -- have you or the team seen zigbee issues with these updates?
Thanks. Reverting did the trick. I needed to re-pair some of my devices, but they are now working (they did not work after re-pairing when I was using 2.3.3).
