It's going to be much slower with a file that size, but it should still work. I just tested a 50 MB PDF with 400 pages and was able to insert another PDF and make changes to the order. If your file is read-only or has some other property that is causing issues with MobileSheets writing to the file, then that's going to be a problem when you insert another PDF into it. If you just change the page order and click "Save", does that work?

This file has protection on it, so that may be it. It hasn't caused any issues in the past though.

If I click the page number field, it opens the rearrange window, and I click the pages field again there and edit it, I can see the preview update correctly, but when I hit save, it stalls.
