Could have told you that was going to happen.
It's been this way for years and I stopped believe it was going to be fixed. When I stopped believing in that was also when I stopped paying.
Unfortunate, disappointing, and seemingly uncharacteristic of a company whose sole purpose is managing notes. It's all great until you leave the world that is Evernote, and when formatting is everything they fall a bit short. Short enough I consider it a failure until this stupid annoying behavior of copy paste is fixed.
