This workaround (negative terminal unplugging) works. This happened to me just 4 days after my brand new truck! Took it to the service manager and he also agreed this is a correct way to resolve it. Unplugged the negative on the 12v LVB, counted 30, plugged it back in. Started the truck and let it be on for a few minutes. Restarted the app and then.... Voila! It started working.
