Styling rich text - mobile defaults

There are defaults for the desktop. h1,h2,h3,p,li etc. but nothing for mobile.

I am building out CMS and noticed that when in mobile there is no option to adjust the default. It only references a desktop view. So I get mega fonts when viewing rich text in mobile.

Any work around?

Thank you!

Here is my public share link: LINK

So my work around is set default “All Paragraphs” for mobile.

Add a style to all P tags vs. use default value.
I’m simply looking for a global P tag without having to assign 2 styles to all my P tags.

Maybe I’m just too needy. But thought this was odd in my workflow.
