THIS: Cannot delete a view in a cloud model. Revit says object is pinned, although its not.

Solved by me and this video.  This is the only way I could find to delete several views that were copies of another view:

Congrats.

I usually delete views in the project browser but I think I understand the limitation.

Yes, I do too, but for some reason that wouldn't work.

The key seems to be selecting some other item (like a detail line) along with the view.  Then delete works.
