Ok, guys – here is the solution:
do not use Twitter sharing code! simply copy/paste tweet URL. Step by step:
1) Copy the URL of tweet.
2) Paste the tweet URL on a line in your article/page (as a plain text) Note : A Tweet link must look like a line, it must be Unlinked.
3) Now Publish it, your tweet will get embedded on your article/page. If it doesn’t work for you, Just edit the page and Unlink the Tweet URL.
Good luck!
