Hasn't Twitter recently been tweaking user feeds based on algorithms? Pretty sure I've been seeing mine out of order, with all manner of "you might have missed" and "stuff we think is relevant to you" tweets injected at the top. I think I recently had to flip a setting to try turning off this "stuff we think is relevant to you" off. Maybe that's the promoted tweets, or are those the ads?
