Since we all know that it's very import to add hashtags it come sometimes look pretty ugly when everything is crammed into the description of the photo.
Would be awesome to have the ability to add a first comment that can be left for your comments.
NOTE FROM LATER: Instagram's API only allows 4 hashtags to be added to a comment. Because we've heard from you that only allowing 4 hashtags would make this feature not useful, we are not planning on implementing this.
Instagram's API details: https://www.instagram.com/developer/endpoints/comments/#post_media_comments
Instagram has allowed this in their API now, but only for Business Accounts. So it is now on our planned roadmap for Business Accounts.
Note: for users who are not IG business accounts, there is a work-around with our Manual Posting that a lot of our Users use: Since Later's mobile app copies the Posts's caption to your phone's clip-board, you can paste this into your first comment on your post manually.
