If you’re posting a tweet (using “Embed Tweet”) and there’s an emoji in the tweet, the HTML breaks after the emoji and it doesn’t post. Even if it looks fine in Preview. TruthWillWin and I figured it out on the previous thread. You have to delete all the emojis from the tweet for it to post correctly.
Or, you can go through the tedious task of adding HTML code to the entire copied tweet to make is display correctly.
