+1 on this, it may just put me over the edge to finally stop using Evernote.
This is the worst of both worlds. Can't disable the spellcheck to stop words from being flagged; and also not integrated with the Mac spelling functions so can't ctrl-click to ignore the word or learn it (add to dictionary). And it's the same on Windows - not specific to platform or language.
Slick dark mode with a bunch of red error-flagged words that I can't do anything about, so frustrating.
If you couldn't integrate it with the native platform capabilities, why didn't you just ship it disabled by default instead of subjecting us to this?
