Samsung Connect Home/SmartThings WiFi - 0.47.10 —all Zigbee devices went offline

Since upgrade I am having OFF Line issues with HUBs, saying they are Off Line along with other devices going offline, but seemed to be working. I have since factory reset and delete app to only now not able to add/extend my HUBs back to Main HUB / Router. When trying to extend to second HUB it gets to 43% and fails. So now down to working with one HUB/Main Router and its Off Line again… Need to roll back upgrade or come up with a patch…
