you can now tap on the new bookmark icon underneath an Instagram post to save it to a separate tab on your profile. What is nice, is that these bookmarks are for your own personal consumption and can only be viewed by you. The real benefit is for the person that loves to revisit posts that impacted them some way, without having to locates someone’s profile and scrolling to find the post. Also saves precious phone space because you no longer have to screenshot the post anymore either.
The New Icon will Look Like This, when the update rolls out to everyone:
The feature works on all posts you find on Instagram, not just your own content. To use the new feature, you’ll have to update your Instagram application first. Instagram released version 10.2 of its mobile app for iOS, Android and Windows 10. Tap the new bookmarks icon that appears in the bottom right corner of a picture or video to save it to your private collection. You can learn more about Saved Posts Here: Instgram Saved Posts
Tracking of old posts will change the way you use instagram for the better. Think of it like a miniaturized version of pinterest for your instagram posts.
