I have had a mesh network for sometime. I tried to connect a new point
and get the message "Could not connect with your NEST WIFI point. I
reset the point and get the same message.
Problem has disappeared and Mesh is working on all connected devices
including iPhone 11. The problem was confined to iPhone 11 as Apple
iPad, TV's and Windows computers all had no problem. I have a sense that
phoen was jumping to a different network...
