content: Good concept but it has issues syncing among devices. I updated the notebooks in PC synced all. On One Drive the content of the note seems to be updated but not the name of the notebooks. On Android phone nothing synced I tried log off and in reinstall the app Clear cache spent so much time trying all solutions offered online nothing worked. I finally gave up had to go back to word and Evernote. The OneNote system sycs poorly and is not trustworthy.
