Let me rephrase my post. I just made post with an Apple emoji in it and although the preview displayed properly, when I posted it, the emoji and everything following it was a blank. I believe this is a new behavior or I would have noticed it before now.
It also happens in Firefox and Brave as well as in Safari. So far I have tested half a dozen different emojis and all of them have the same effect. I know this is new behavior as I have used all these emojis in posts for years.
