I was reorganizing and selected one page, used the 'move' option on a mac laptop, and moved it to a different section. Now it shows up as 'Untitled Page', and the page has said 'loading' on all synced devices for the past 24 hours. Other users of the notebook now see a message at the top of the section that I originally moved this page from, which says "It looks like this section file is corrupted. OneNote might be able to fix it, but you should avoid working here in the meantime". I do not understand how to get the page back that I moved, or how to get onenote to try and fix the corrupted files since it doesn't appear to be trying to fix anything at current. It is very important that I be able to retrieve the missing page, the information is evidently not backed up from what I can find (an issue for another day) and cannot be replaced, so obviously I am quite concerned and frustrated.
