DH was told on 22 Dec that he’d tested positive and DD and I received stern messages through the NHS app telling us to isolate till midnight on the 31st. Then DH was phoned and he gave them both mine and DD’s contact details. DD received an email and a text saying isolation ends on 29th Dec but I’ve had nothing. Should I still be obeying what the app tells me as that’s the only communication I’ve had?
