@Desiree133 I know, that new calendar view is awful, at least for me.
To get the full month calendar view, you can either go to your edit listing page and near the top right, click on Calendar, or go to where you see that line calendar view, look to the left of that where it has your listing title at the top and click the arrow next to it.
It's so absurd that they change things without letting us know where and how to access the things we are used to and that work better for us.
