I moved home and my old account was disconnected yesterday and the new account is being connected today. The engineer is supposed to be coming between 1pm and 6pm and I was told I could check for a more specific time slot on the day through the app. However, the app is connected to my old account which has no appointments connected to it so I can't check anything.
