I have invested in 18 Tapo devices including 5 external cameras.  I have just upgraded my Broadband. I was able to update the Router on Homebase H500 without any problem.  It apears that on the other 17 devices I have to remove them and then add them back. To make it worse I also loose the settings on each device.  This seems to be unique to Tapo and Kasa (Both TP-Link) devices. Surely this is utter maddness.  I hope TP-Link can get this sorted.
