It can be cumbersome sharing a photo to Twitter and @mentioning someone whose Twitter username is different from their Instagram username. Today, we’ve rolled out a change that will make sharing to Twitter more seamless.

For photos shared to Twitter, Instagram now translates @mentions for users whose Twitter username and Instagram username differ.

If the @mentioned user has connected Instagram to Twitter:

  • The user’s Instagram username will appear in the photo caption
  • The user’s Twitter username will appear in the tweet

If the @mentioned user has not connected Instagram to Twitter:

  • The user’s Instagram username will appear in the photo caption
  • The @ sign will be removed from the username when shared to Twitter

For @mentions that do not match any Instagram usernames, the @ sign will remain when shared to Twitter.
