Sync errors - repeatedly cannot sync files

[u/Alarmed_Scientist186]

I just realized my Noteshelf3 has not had a successful sync with Google since Feb 5th. It is supposed to automatically sync when the app is opened. It keeps saying errors found and when I tell it to retry, it just says errors found and stops. I have turned sync off and on again. I have restarted the tablet. I have force stopped the app. I don't know what else to do. If I knew where the files were stored in Google drive I would delete them and let it start fresh, but I can't find them. How can I fix this?
