I have had my 830 for a few months now. I have never been able to view my ride in the app when finished unless I have cell service. I have to get home and have the 830 connect to wifi and upload the ride and then check it in the app. If I have cell service at the end then I can see my ride on my phone so it is possible to sync with my phone, Also, my phone is connected to the 830 as I can receive texts during the ride if I happen across cell service. Is it possible to view a ride on my phone without cell service? If so, am I missing a setup switch? My phone is an up to date iPhone.
