Instagram adds location and hashtag stories to Explore tab

Moreover, Instagram users can now discover stories happening at just about any location around the world by using the story ring for that place at the top of the location page.

The hashtag stories feature on Explore allows users to find stories related to their interests. Instagram users who include a location sticker or hashtag to their stories may be added to a larger story. If you want privacy, you can tap the X on your stories viewer list so that your story won't appear on Explore.
Keep in mind that location stories on Explore are already available on Android and iOS devices for users who update to version 10.22 via Google Play and App Store. The hashtag stories feature will be rolled out over the coming weeks.
