Ok, well I have no issues on my Samsung Tab A 2016 (P585Y) running Android 8.1.0 (Oreo), Samsung Experience 9.5, Build M1AJQ.P585YDXU2CRJ9. Running Evernote 8.6.1.
Are you running the same model? What are you running in terms of app and O/S?
The Samsung keyboard is updated with a different layout for accessing handwriting. So while you're blaming Evernote, it seems likely that Samsung was the non-compliant party.
