I retired one of my cars using the web interface at fuelly.com. When I use the GasTracker or GasCubby app on an iPhone, the car is still visible in my garage. I tried to resync my data from the app but the car is still displayed. Any ideas before I try to retire the car via the app?
I too have experienced this a half dozen times or so, this morning being the latest occurrence. Logging out and back in does remove the retired vehicles again. Version: 3.3.12, Build: 1237
