Markdown for RTF does not appear to be working in Mojave. I installed the Multimarkdown and Multimarkdown Support binaries and installed them using the standard installer. I then installed the Markdown Service Tools v2.16 and tested out on some markdown I had in Evernote. Worked like a charm...the first time. Next run...

Automator encountered an error running this workflow: “Couldn’t communicate with a helper application.”

Any thoughts?
