Make sure your using version 4 Excel AddIn. There used to be a limitation preventing you from using saved views but that has been removed with the new version. Also, there used to be a 1MM insert cell limit but has also been resolved as of April. Lastly, With the Excel Add-in (from 4.0), you can contact Anaplan Support directly from the ribbon, by choosing "Help" and then "Contact Support". This generates a pre-populated support email with technical information attached and at the bottom, as well as a set of questions for you to answer in order to help our support team understand your concern.
