By completing that simple step, you are far ahead of most Marketers with regards to using Twitter. This Particular tweet which you have chosen to feature will need to be replaced from time to time so let's review how we remove the Featured Tweet.

Go back to your Profile Page, (tweets, tweets & Replies, Media)

Locate your featured tweet which is at the very Top of your list of Tweets and go down to the icons once again and click the three bullets. Once you have completed this, another Menu will appear(see below)

Simply select the Unpin from profile page and the next time you post a tweet it will automatically take over the top position UNLESS you decide to pin another tweet which i would highly recommend.
