There’s no longer a way to preview posts on mobile when using the markdown editor. There used to be a button in the bottom-right section for this, but it has disappeared. If it has been moved somewhere else, I can’t find it…
Brought this up a few days ago:
I noticed that, but in my experience the wysiwyg editor frequently breaks markdown, so I don’t see how that’s a valid option. Unless all the issues I had with it earlier this year have now been fixed.
the other option is to turn your mobile phone sideways (landscape) and see the previewer in wider viewport
