Twitter had long back enabled location sharing feature for Tweets where you could add you location and coordinates along with Tweets. While some people found it useful other found privacy concerns with it. If you have enabled location sharing on any of your previous tweets and want to delete them now, then Twitter offers a quick way to delete all location information from previous tweets in one go.
To delete your location information, you need to log in to Twitter web. Once logged in, select the profile icon on the top navigation bar and select Settings.
Under settings, you will see the button “Delete all Location information” listed under Tweet Location.
Once you click it, Twitter will ask a confirmation and it might take few minutes before all the location information are deleted. If you have a lot of tweets, then probably it might take more than 30 minutes or so. Once you delete all the tweet location, make sure you uncheck the option “Add a location to my Tweets” above.
