A recent change to Chrome has resulted in the Map to continuously be redirected, so that it never opens. This is linked to a user's account on a given machine. So they will not experience the same problem on a different machine, nor will others experience the problem on the user's machine. This can be resolved following the instructions below.

  1. Export bookmarks before doing this, as described here https://support.google.com/chrome/answer/96816?hl=en:
  2. On your computer, open Chrome.
  3. At the top right, click More More.
  4. Select Bookmarks and then Bookmark Manager.
  5.  At the top, click More More and then Export Bookmarks.
  6. Replace <username> with the name of your user folder in the following and navigate to the location in File Explorer by entering the following editing and then entering the following address:
    C:\Users\<username>\AppData\Local\Google\Chrome\User Data
    It may be necessary to making hidden folders visible so that the AppData folder will show 
  7. Delete that entire User Data folder 
  8. Open chrome again
  9. Sign in to google and sync to bring back bookmarks and stuff.
