Because of its adoption of a perfectly opaque and ridiculous “block editor,” and its demand of a $275 ransom (upgrade to “Business Plan”) to get back the old editor via a “plug-in,” I am suspending postings on this blog.
Follow me instead on these two blogs:
Blot (fairly unfiltered)
Microblog (nicer)
Tipsy Teetotaler ن 
Brother, on iOS I am able to switch to the classic editor at will. See if that is the case for you.
I figured out how to post using my external Markdown editor, and I expect to resume posting as soon as today.
Sorry, I should have specified that I use the WordPress iOS app.
