Getting 'unable to collaborate' message; but I am not attempting to collaborate
In Keynote for the iPad, I am getting this message popping up as soon as I open the presentation. This is happening on one presentation only, but not every time I open it.
I am merely opening the presentation to show in my classroom. I am doing nothing, (as far as I know) to tell Keynote that I want to collaborate with anyone on this presentation. Where is the setting to turn this off?
