How should Custom Message Fields be set up for the New Jira Issue View?

[Kathy Hart]

My Custom Message Fields for View are not working correctly with the new view. You do not see a pretty colored panel box with the instructions in the main part of the page. The field is relegated to the right hand column and shows the code for the panel as well as the wording within the panel. 

First screen show below is the new view, the one below it is the old layout. What is the plan for how Message fields will show up in the view?

Hello Kathy,

The new issue view uses markdown formatting now and not wiki markup, that's why the panel does not work.
You can find more information here: New Atlassian editor

"The editor in the new issue view uses markdown rather than wiki markup. Right now, if you've added wiki markup in the old editor, we'll render it correctly in the new issue view. As we continue to roll out the new issue view and new editor, wiki markup support will be phased out and eventually removed in favor of markdown"

I've searched on our documentation and also on the markdown guide, but there is nothing equivalent to the panel.

Regards,
Angélica
