Annotate PDF error

[GMAC 0]

My iPad version of evernote does not allow me to annotate PDF attachments. I just moved from goodnotes and this is one of the key features i need.

I'm on iPad Pro 12.9-inch 2nd Gen - MPLJ2X/A running 13.5.1 ios with evernote app 8.24.6

Whenever I click the "annotate" button it says "Could not load the document: Unable to read document".

The PDF shows correctly on screen, in the note. It just won't start the annotation editor (to place arrows, add review marks etc.). I've tried different PDF's and its the same issue with all of them.

I've also tried logging out and reinstalling the app but it still won't work.

Any help would be greatly appreciated!
