You can change the view type in two ways. Either through the "Settings" tab or in the "Organizer" tab.
In the "Settings" tab, select a view type from the "Default view type" dropdown menu. This setting will apply when you login to your Organizer. Meanwhile, if you change the view using the top menu, the top menu view will apply until you logout of your account.
You can also change the view type temporarily in the "Organizer" tab using the Calendar's top menu:
If you make any changes in your Organizer settings, don't forget to click on the "Save settings" button so that your changes will take effect.
