Mine worked for the first time this morning. The app still gave me the error saying it had failed but when I got in the car was toasty warm and fully defrosted. First time its ever worked for me. Also having it preheated whilst plugged in bumped my efficiency up to 3.5miles/kwh on my 25mile A road/ motorway commute this morning! Ive not been able to get it above 2.7 previouslyAnybody else noticed the graphics change on the app for the air conditioning screen? Use to show a picture of the car interior, now more basic. Got excited thought it might work without car plugged in but no!
