I see 10GB in ~/Library/Containers/com.apple.STMFramework.UIHelper.com.evernote.Evernote/Data/Library/Application Support and 12GB in ~/Library/Group Containers/XXXXXX.com.evernote.Evernote. But I just realised that the first one seems to be more than a year old from when I moved from the App Store version back to the Direct download version. So I will remove the first folder and see. 

Ok, so I switched to the non-App Store version of Evernote and it works great. So, seems like maybe Apple changes some limitations of the app sandboxing.

Thanks DTLow and macfixer ! I already have Preview as my default for PDFs in Evernote. The problem is when annotating Preview makes a copy of the PDF and wants to save it on my Desktop rather than back into Evernote. So I have to then manually drag it back from the desktop and replace the previous PDF saved in the Evernote. I believe that Evernote used to work, and this is a bug that have crept back in. I'm running:

Version 7.9.1 (457703 App Store)
Editor: 62.3.7750 (ee6e44e)

on MacOS Mojave 10.14.4 (18E226)

I know that Evernote integrates Skitch for annotating PDFs, but I would like to use the Mac Preview app instead (I find the text highlighting in Preview better). But I can't find a setting to launch Preview for annotation rather than Skitch. Is there a hidden option somewhere or some way to achieve this?
