I have been using the annotation feature in Evernote (Windows) for the past 2 days. It worked fine the first day, but today it won't function correctly. I annotated a PDF today for about an hour and then I received an error message reading "This resource has changed unexpectedly or has been deleted externally. Please save a copy in a new note or try again later."
I tried opening the PDF again and annotating, but received this message again after 2 minutes. I tried troubleshooting for a while but continued to get the same Error message. I turned off the sync, tried a local EN notebook, and tinkered with some other settings. I purchased EN Premium primarily for the annotation function, so for it not to work is disappointing. Someone please help!!
