Media Settings don't change

Also tried to change the embed size in my child theme functions per this page but no change …

I’ve restored version 6.5.2 of your plugin until I get this resolved.

Does the plugin leave something in config or functions or the database that I need to remove?

Here’s the correct way to change embed sizes:

And yes, my old plugin (not my new one) leaves an option in the database. That doesn’t cause any additional database queries having it there.

In the future I may have my migration plugin delete the option.

That did it. All the old posts and new posts now have the correct video size. The small video size in WPTouch when holding the phone vertically is also much better.

Thanks!
