Since updating Garmin Connect to 2.9 on my iPhone, Live Track is missing as an option from the menu. I've tried uninstalling and reinstalling, deleting and readding both of my 510s, but nothing.
Under App Diagnostics, Live Tracking Extend Sharing is set to "No", and this is nothing that I've done. All of my privacy settings are set to allow Everyone to view my activities, and I've tried every setting available on the devices and app with no luck. This is the only aspect of Garmin's software that I ever use, so it's pretty infuriating that it doesn't work.
Most of my bike club has been asking if they should upgrade older Garmins and non-Garmins to the 510 or 810, and I have started telling them not to, since support is next to non-existent, and I spend more time messing around with things just to get them to work than actually using the device and software. Not good.
