Does anyone know why some of the options for automatically creating keyframes in an animation in ArcGIS Pro (as per this documentation) are greyed out (the bookmarks and range slider options), and others (the circle around selection options, which is what I want to be able to do) do not show at all (see attached screenshot)? The map is a 3D scene with 3D data, and when the screenshot was taken the camera was viewing at an oblique angle (ie not directly above), and there was a feature selected.
I am running ArcGIS Pro 2.4.2.
All suggestions greatly appreciated!
