Ok, I'm feeling really stupid right now for asking this, but where do I find this setting in windows 8.1?
I've looked for a while and can't find it.
I also have a 190MB notebook that was syncing perfectly. Now it is glacially slow - I'm still waiting for it to sync a 130 page printout and it hasn't finished it all over the past 3 days.
To test the file size theory, I made a brand new section with just this printout in it and nothing else. It takes forever even though the file to by synced is only 20MB. This all worked very quickly up until the end of June 2015 and I haven't changed what I do at all.
I have to operate this way as other teachers make the notes which I then print to a notebook and annotate along with my students. All my annotations are in a shared notebook which they can access when sick. So please don't tell me to stop using printouts etc. as it worked perfectly for 6 months and has now come to a grinding halt. I would like to change the sync setting - if only I could find it!
