Commute to work on Google Maps tracking is innacurate
Firstly a possibility to the app is tracking two different phones at once is quite impossible. Even though you tried on all the forums already, I suggest you to do a simple way.


If you are using Android, go to "settings" -> find  "apps" -> click on "maps" and then stop it.
Restart your phone and open "maps" app again.


This has already happened with friends and instruction above was the solution for it.
