**Update** Seems to have corrected with the last update to the app. I haven't had any issues since then. *** Stopped Working! Liked the change from hold to start to just press. But now I'm receiving error message when I open the app the button says 0.00 not start. When pressed it shows error Invalid date and the timer is at 0.00 and won't reset.

I try to really use this app as much as I can, but even with the update, I am STILL having issues. While it's not as slow and clunky, and bugs have been fixed, I get frustrated trying to do anything other than starting my car. I've been attempting for two days to schedule a service appointment, and BOTH times it was unsuccessful. I triple checked everything, and yet, it keeps telling me to contact the dealership with no reason as to WHY it is unsucessful. I REALLY want to utilize the app more.

I'm a little disappointed, the app will not update my status, whether it is gas, oil status or anything like that. it's been over 2 months and still nothing. starting, locking, unlocking, etc...the app works fine but that's about it. I've uninstalled and reinstalled it, logged out and logged back in. so this will get a 1 star until you fix.
