Not sure I missed something.
I went to the settings, turned on the HTML storage and clicked migrate. This seems to take a while so I moved on with something else on another site.
The notes say clicking migrate is basically a toggle.
As there was no message when I returned to the site I’m using to test the beta, I have no clue if it was successful or not or which engine I’m using.
My question, how do we know if we are using the HTML storage or the shortcodes? Is it possible you can add something to indicate clearly which storage engine we are on?
