I have a solution!
It is more of a work around than a direct solution, but it is simple and it works.
Copy the url of the tweet you want to embed and paste into your post. Then publish the post. To embed it, you have to then edit the post. Place your cursor at the end of the url, and hit enter.
Tweet changes to an embedded tweet. Then update the post.
Since I wasn't smart enough to figure this out myself, mad props to my main man Shep, was says he "stumbled" across it. Wonder how many he had in him at that time? 🤪
