I'm genuinely curious, how would elements of a document that were previously not imported into Pages automatically appear due to a software update that now allows these elements to be imported?
The big takeaway from this software update is that has acknowledged that the lack of footnotes was an issue in Pages for iOS. As it stands now, the only thing missing in basic functionality is the ability to add a note. We can edit existing notes and those will be exported. I imagine the next significant Pages update will increase functionality to be able to add notes natively.
