Zotero highlights disappeared when reopening the pdf
i've read a 200 page report and reopened the app to re-view the pdf and all the highlights have gone. I have sync on etc., and haven't got the pdf saved elsewhere. Please help!
2. When was the last time the annotations were present?
3. Do you use Zotero on other devices or computers?
4. Were these highlights created in Zotero or imported from a PDF file?
2. about an hour before, then the file closed and i had to reopen and they were gone
3. only use zotero on one device
4. highlights created in zotero
thank you so much for your help!
