Good luck...
I have the latest iMac, MacBook Pro, Apple Watch, etc and this app only has ever worked on initial install/first day and then pretty much never worked again. It simply doesnt find the phone and they have no real simple support solution for this.
If I uninstall and reinstall I go through the cycle again. Done it multiple times now and this app sounds good but really is more trouble than its worth.
