I can tell you that it doesn't matter WHAT size the PDF, JPG, PNG or m4a. **NONE** of my YEARS' worth of attachments -- which were accessible to me before installing the latest version of Evernote -- are able to be displayed now. I can see the content still exists because it shows up in my browser access (even though the Note counts/content in the browser do NOT match up with nor, display what my Notebooks actually contain) and, my iPhone will display attachments but, I can't see any of that content on my desktop version (MacOS Catalina 10.15.6). Which I think is beyond ridiculous.
I'm not tech-savvy enough to know or execute a work-around, IF an older version of either/both my OS or, Evernote would resolve this issue. I also don't think I should have to experience loss of access to note content, simply by reinstalling Evernote and getting the latest version!
Is there a the pathway for a NON-tech geek like me to be able to use the desktop version again to view and share the content I created??
