If you want to specify what page a provider lands on immediately when they log in, then the Providers/Instructors area is where to look. Here's how you can edit that default view for each provider in your account:
Head to Settings and navigate to the "Providers/Instructors" tile
Select the provider you would like to edit
Select the “edit” button on the Details page
Specify which landing page you would like for that provider. You can choose the appointment calendar, the class calendar, the dashboard, or the workshop listing
Save your changes when you’re done!
When the provider next logs on, they will be directed to the default landing page that is specified under their Provider settings.
