I am getting a bit closer to a workaround
@ckmk47. I don't know exactly what I did, but I did it twice so far. I think it sort of went like this:
Before I posted (which turns out miniscule because of the unwanted [size] inserts), I copied just the picture of the Wordle scores, posted, selected 'Modify message' icon on right side [Did you even know that was there?!], typed the word parts, then pasted just the picture. It comes out with random colorless boxes when posted, but the words come out the right size. Then I went back into "Modify" above and pasted the picture.
So Techies, any idea of what is going on? [/size]
