I have been unable to sync my recent Notebook to OneNote 2016. When I click file -> view sync status, underneath the notebook it says, “We’re sorry, something went wrong during sync. We’ll try again later. (Error code: 0xE0190190)”. I have tried searching on the help site however I am unable to find an answer. I have instead exported the document to a PDF and saved it that way, though I would like it to sync as it should. Any help is appreciated!
