I published then deleted a rant about using this site. A bit of reflection reminded me that we can find anything on the web. I went to DuckDuckGo and asked how to revert to classic editor in WordPress. Turns out, it’s a one click fix, and I can indent all my paragraphs.
When you are on the editing screen, click on the ‘. . .’ settings icon in the upper right corner of the editing screen and click on Switch to Classic Editor option from the list. (See the screenshot below)
