I dragged and dropped one section of a notebook into it's own notebook, then split it up into several different sections by highlighting pages and dragging and dropping into new section tabs. When I was done, the first section got an error that says "Waiting to sync this section. Another Onenote created it but it has not uploaded the content". I can't get the data and when I went to file / open backup the notebook isn't even there! Is there any way I can recover this data? I have tried closing it and re-opening it (which I was hesitant to do since apparently it has no backup) and nothing seems to work. Please help.
