My scheduling grid is blank!

When you first login to Astra, you have to tell it what calendar filter to use before it will pull data into the grid.  Usually Astra will remember what calendar you selected the next time you login, but sometimes a browser cache refresh or some other system change will cause Astra to forget this setting.

In the daily grid view, make sure the "Choose Calendar" drop-down list is set to "Main Campus." The grid should refresh.
