Some problems with Mailtrack can be solved by updating the Mailtrack extension.
Chrome usually pushes extension updates gradually over a few hours/days. If you want to force an update of the Mailtrack extension in order to speed up the process you can do so manually:
1) Open a new tab in Chrome, copy/paste chrome://extensions/?id=ndnaehgpjlnokgebbaldlmgkapkpjkkb into the address bar then press enter.
2) Enable the Developer mode option in the top right-hand corner of the screen then click on the Update button.
If this doesn't work, reinstall the Mailtrack extension on your browser. Instructions explaining how this can be done can be found here.
