Has this just occurred if so yes I have it followed a large area loss of service yesterday hub reset mostly to defaults when service resumed Do a hard reset by use of pin in the hole above the switch’s with power on and start again did it for me
Answer #2
BT server was down yesterday so just do a reset if that doesn’t work then try Reset to Default
