a known bubble bug. apparently from “poor internet connection” and using multiple tabs for the editor
I’ve reached out to support to log the issue several times but no fix yet (reached out over a year ago)
I regularly have work that I’ve done go missing. Just have to redo it. Annoying as hell but there’s no way I could work out of 1 editor tab. (I’m often copying and pasting from other pages, looking at other pages styles/layouts etc)
