We just upgraded on our work computer and having the same issue. Huge disappointment that the only way to insert a file, or delete a range of pages, is in thumbnail view. In the previous version you could do delete a range of pages in "page view" and just delineating the range of pages to be deleted. Same with inserting pages - this could be done in "page view." Having to use "thumbnails" and select, etc. is terrible. Bring back the old features that worked well!!
