From time to time, ESRI resets the map tokens that Tablet Command and TC Mobile uses to display ESRI maps. To reset your ESRI token: 

  1. login to https://api.tabletcommand.com 
  2. Along the left hand navigation, click on "Settings"
  3. Under the ESRI Token spot, click on "Login"
  4. Login to ESRI using your named user account
  5. The token will reset.  It is normal for the interface to say that the token will expire, it will continue to be renewed until ESRI clears the token.  This can be two weeks, two months or even as long as a year in our experience.
