If you don't want to see Instagram posts or stories from a particular user, you can mute their stories or posts without having to unfollow or block them. Also, they will never know you have muted them.
Muting a user means you're still connected to them (i.e., you still follow them), but their content no longer appears in your home feed, and you won't see their stories. If you mute a person, they can still see your posts and stories.
How to Mute an Instagram User's Posts and Stories
Posts appear in your feed. Stories appear at the top of your feed in a horizontal line as profile images. Here's how to stop seeing either or both for a particular user.
Sign into Instagram and navigate to the user's Instagram page. You can select the search icon and enter their name in the search bar.
On their Instagram page, select Following below their profile image.
Mute posts by setting the Posts switch on. Mute stories by setting the Stories switch on.
The user's profile image will turn slightly transparent, and their stories will show at the end of your feed.
You can also mute a user directly from your feed. To mute a user from your feed, tap the three dots next to their name > Mute > Mute Posts or Mute Posts and Story.
How to Unmute a User's Posts or Stories
To unmute a user's posts or stories:
Navigate to the muted user's Instagram page.
Tap Following below their profile image.
Unmute posts by turning the Posts switch off. Unmute stories by turning the Stories switch off.
How to See Who You've Muted
Forgot who you muted? Instagram keeps a running list of your muted users in your privacy settings.
Tap your profile image.
Tap the menu icon in the upper-right corner.
Under Connections, select Muted Accounts.
Select any user to go to their Instagram page and optionally unmute them by following the steps in the section above.
You can still view muted users' stories by going to the end of your stories and tapping their transparent profile image or by visiting their Instagram page. Muting only prevents them from showing up in your stories feed.
