HEY!!! Version 6.9.2 has a beta option for codeblock! No syntax formatting though. So stupid. Quiver is still way better.
This request has been going on for years. Clearly Evernote is not interested in implementing it even though users like us are the core of their business. I suggest we all use Quiver instead. It is made for code and is practically identical to Evernote. https://itunes.apple.com/us/app/quiver-programmers-notebook/id866773894?mt=12
