I took delivery of my Dolphin Comfort 3 weeks ago. I’m new to both EVs & Automatics so on a huge learning curve. Tried to add my vehicle to the BYD app but it asks to scan a QR code. Tried the one next to the VIN but is says expired. Anyone any idea? Also mine is not that accurate on mileage. I regularly do a trip which I know is 71 miles but even driving economically it uses over 100 miles of charge.
