Instagram is rolling out another new feature today, and this one is aimed at making user profiles better.
Instagram says that live hashtags and profile links are being added to bios. This means that if you include a hashtag or @ user name in your profile, they'll now be live links that will send a person to the live hashtag page or user profile when tapped.
This is a small tweak, but it's one that makes Instagram user profiles better. Most people probably expected to be able to tap a hashtag or user name and be able to go to the page for that hashtag or user, especially since that's how it works in regular Instagram posts. Now it'll work that way in user profiles, too.
One other detail of note is that when you mention someone's profile in your bio, they'll receive a notification and can choose to remove the link. If they do, their profile name will still be in your bio, but the link will no longer work.
