Lately the app doesn't choose que quickest Journey... I check on the laptop and there's always a quicker way but the app doesn't identify that way. However, if I then go through the quicker route, it rectifies. It makes no sense. EDIT: still rubbish! The issue is with the app and the steps I was given are for the laptop. The app keeps sending us through back routes instead of the motorway. And no, we didn't choose for it not to use motorways!!!
