The description of Instagram Lite
Specifically, you can use Instagram Lite to:
• Post photos you want to keep on your profile grid and edit them with filters.
• Share multiple photos to your story. Bring them to life with text. They disappear after 24 hours and won't appear on your profile grid or in feed.
• Watch stories from the people you follow in a bar at the top of your feed.
• Discover stories, photos and videos you might like and follow new accounts on the Explore tab.
• Now you can send messages to your friends.
