I've tried everything mentioned in this thread and then some, and I still get the 'Connection Lost' prompt as soon as the app comes up, Demo Mode, no bike data, etc. I rented an iPhone 5 thinking that would minimize the chance of problems since the app "is optimized for iPhone 5", yeah right.
I have no trouble connecting the phone to the bike via Bluetooth, but the app never sees the bike. The call-back I was promised from Zero support never came, as usual.
Can the app be shut down (i.e., stopped completely) without being removed from the phone? The only options I can find are flicking it away (which seems to leave it running in the background) and deleting/uninstalling it by holding down the icon, after which the icon's gone and I have to log into the app store and download/install it again. Is there a 3rd way that just turns it off?
