iPad preview mode

How do I switch from Editor mode to Preview mode on iPad? Is there even a manual?

I found something about Source mode </> here, but I don’t even have the three vertical dots at the top right?

There are three views. Source and Live Preview are editing views, and Reading is the reading view.

On mobile, pull down to open the command palette.

  • While in either of the editing views:
    • Select Toggle Live Preview/Source mode to switch to the other editing view.
    • Select Toggle reading view to switch to Reading.
  • While in Reading:
    • Select Toggle reading view to switch to your most recent editing view.
