UConnect does not update in real-time.

[Gellie]

Tired every from updating to uninstalling/reinstalling app. Info says updated 4 day’s ago. Obviously trying to use this app to see your current fuel level is a waste of time. Chatted with the developer site and was of no help. I hope they don’t expect me to pay for this service once the trial is over.

It probably has more to do with the communications between their servers and the Jeep. That said the service has little to no value to me. I think I used it once or twice to confirm that I locked my Jeep remotely once. Never used it for starting. If it was $3 a month for XM and all the other Uconnect stuff you get for free for the first year I'd maybe consider it.
