I'd like to jump in on this one as well. Completely frustrating that my preferred writing tool doesn't help with spellcheck. The fact that it recognizes a suspect spelling (and underlines it) yet cannot do anything about it is beyond reality.
I really have to wonder why I'm paying for a premium account when a most fundamental thing is (seemingly) missing.
And from my numerous attempts to find an answer on the web this is all I find:
Please, Evernote Team, help us faithful, paying customers... this is a step backwards. This sued to work... or am I mis-remembering? Is it something we need ot enable on the OS side of things? If so, how?

Many, many thanks in advance for a helpful response!
