You might try the steps listed on the Glance website or the troubleshooting steps on this page if you haven't already.

@MonikaK1 Unfortunately your response is not helpful. Only very generic items are listed, which don't mention any errors I am observing. In addition Glanse support hasn't responded on the ticket I filed and email I sent several days ago.
