So I'm in the app, with a note open, I click the three dots, select 'add to homescreen'.
The problem is that the newly created shortcut doesn't work IF Evernote is already open. All it does is open Evernote on whatever note was previously open. However if Evernote is closed, the shortcut works fine.
What's even more mysterious is that my older home screen shortcuts work fine all the time. It's just all recent shortcuts I've added which don't work. I did recently downgrade from premium to free, could this be related?
