I took over another line on my account and will be dropping the line I had previously set up my son’s Gizmo with (he had a Gadget, now has the Watch). I CANNOT figure out how to either edit my number or delete me in his contacts to re-add with my new number! I’ve removed and re-added him, I’ve removed and re-added the device...NOTHING IS WORKING! There is no edit option for my info as I was set up as the primary caregiver. But surely there has to be a way to change this?! Please help!
