My footer comments were restored successfully, but they seem out of order and aren’t posted by the original user.
This is a known issue and we are working on a fix to make the comments come in, in order. As for the user not being the same as before: the Confluence API prevents anyone from posting a comment on behalf of another user. Instead, we insert a line of text into the comment, identifying the original poster and the time they posted it.
An inline comment failed to restore
Due to an API limitation, inline comments fail to restore if the word that was selected appears more than once in the document.
