When I enable tracking with share an invalid web address is e-mailed to my home contacts. The invalid address sent is: https://us0-share.inreach.garmin.com/NCWPT How to fix this?
Have you recently changed your MapShare URL? Log into your account on inreach.garmin.com. Click the Social tab. In the MapShare section (upper left), you will see your MapShare URL. You can control the last part of the URL (after the last slash) by clicking the Edit link next to the URL. Read the warnings carefully. Basically, if you make a change here, the old URL becomes invalid. Anyone who previously received that link will be greeted by the "Whoops This MapShare URL does not exist" message if they use the link.
If you have not changed the URL, or if you are getting the problem with the URL which is sent "right now", then I'd suggest a call to tech support.
