I have been running 6 Tapo devices with no problems for about 3 years. Yesterday I upgraded my nework and have been unable toconnect ANY device. Using aP110 as an example. It flashes green & orange. Ifollow reconnect device to wifi. All goes smoothly - it finds the device, it finds the network, it tries to pair the device. Light goes to orange flashing. After a minute or so it returns to oramge green flahing. I have let it run for 2 or 3 minutes but nothing. I have tried this with several different devices both without deleting the original device and after having deleted it. Not a glimmer - it hangs on the pairing process. Any observations/suggestions gratefully accepted
