I have Keynote 6.6.2 on a MB Pro running 10.11.6. I have imported 2 powerpoint files and edited them, and now I get "Couldn't Autosave document" when I try to save, duplicate or export either of them. I had this before and saving to desktop bypassed the problem, but now it doesn't work either. Seems like this problem has been going on for years looking at the fora, and it's time Apple fixed it. Any ideas please?
MacBook Pro (13-inch Mid 2012), OS 10.11.6
