Just installed an update to Acrobat yesterday and noticed this morning that I'm not able to drag and drop pages between 2 PDFs. I have turned off protected mode at startup as well as enhanced security and still nothing. This was the single feature I used the most out of the entire Acrobat software. I don't know if I'm missing some new setting or not. If not, please fix this bug or bring it back if it was intentionally removed. It was already painful in that you had to go into each open PDF and go to organize pages in order to drag and drop. Now it's gone completely and I'll happily suggest to my IT team to seek other alternatives to Acrobat if this isn't resolved.
