Map frame cut-off? Like a letterbox view

[TheodoreF]

In the latest ArcGIS Pro, one of my maps appears to be missing the top and bottom of the frame. Why is this? I haven't changed any map settings. How can I get it to fill the whole frame? Other maps in my project are fine.

The first thing that comes to mind is that you were doing something with an animation and have the Lock View Size enabled.

Is that it?
