I have same problem. Ever since updating and it is terrible - I start phone calls and can't pull up notes from my last call.
it is SERIOUSLY BROKEN - please advise what to do to make all my shared notes sync and be available when I need them.
Even the "release notes" box doesn't display correctly. Sometimes restarting fixes it.
This time I was able to restart and fix it: "Evernote v10.4.3 build 2071 public, on Catalina on a Macbook Pro"
