Steps to add an Instagram note
To begin, run the DMs tab on your Instagram application
Tap the “Your Note” button to open a new page
Add a Note
Your followers will be able to view the letter for the next 24 hours once you’ve completed composing it. Followers may even respond to these Notes if they so want.
You will have the same two options for choosing your audience for the Note as you do for Instagram Stories: Close Friends and Followers who you follow.
