Within Vidyard, you are able to select a custom date range in many areas of the system, such as the Analytics Center and Dashboard.
In a previous session, you have changed the custom date range to something other than the default, but it goes back to the 'past 30 days' option when you return to the page.
Each page where there is a time frame option is designed to show information from the past 30 days. Therefore it will always use this as a default until a new selection is made.
There is no option to change the default time period at this time. Therefore you will need to make an appropriate time frame selection on each page visit.
