data-tweet-limit removes the “Load more” button which may help your case.
“Tweet limit: To fix the size of a timeline to a preset number of Tweets, use the data-tweet-limit=“5” attribute with any value between 1 and 20 Tweets. The timeline will render the specified number of Tweets from the timeline, expanding the height of the widget to display all Tweets without scrolling. Since the widget is of a fixed size, it will not poll for updates when using this option.”
