Rendering Markdown in Emailnotifications

1

Hi somehow this has never worked for me. Bug was reported, solved and closed 2 years ago:

I am using Mattermost 9.4.1 on a self hosted server.

I don’t know if this requires an extra config value.
We send bulk email notifications but all markdown parts as well as Emojis are not converted to html.

Any idea what the reason could be?
