I am using Windows Desktop app version 10.18.3.
When attempting to open an attached PDF file in Adobe Acrobat, I get a message stating "There was an error opening this document. This file cannot be found." Similarly, if I save the same attachment using Save As to Windows, the resulting file is unreadable.
When I try these same actions, for the very same note & attachment, using legacy Evernote, the attachment opens right up. Save As work fine, as well.
Something is not working right. any suggestions?
