Oh thing occurs to me– at one point, I found I did have multiple dashboard pages open. I didn’t realize at first that “viewing” my page opened it in a new tab, so when I clicked to go back to edit mode, I was now editing in that new tab. So I closed several & tried to stay within just the one. Do you think I could have been somehow working in an inactive mode (again, terminology- ugh. do you know what I mean?)
