Hi there, I have two fairly large problems with footnotes in the latest version of Manuscripts.
The first is that it is impossible right now to paste anything copied from the document into the footnote. Copying plain text from elsewhere and pasting it in works however.
Secondly, footnotes do not have any numbering and do not show up in text when exporting to word.
Finally, there are some minor cosmetic cursor problems when trying to select the end of a line ending with a footnote.
I've attached a minimal Manuscripts document showing these issues, as well as the exported Word file and a manually corrected version of the export. Hopefully that helps fix the issue. You can find that here
