Yeah, but you're not going to like it. Miracast hasn't really caught on. It's buggy. That's not to say "Well, that's just Mircacast" but do be aware that there's a reason that Android dropped Miracast support seven years ago.
Now, I've not used it, but only because that's not functionality that I care about. But I have followed along. I'm only chiming in as I am aware that it's functionality is sometimes problematic, and no one else has offered anything. I'm setting your expectations low. I do wish I had an answer to assist, but apart from resetting your expectations, my response may also bump the thread and give it visibility to those that may have something much more useful to offer.
