To determine if someone has hidden their Instagram Story from you, follow these steps:

  1. Check for Highlights: Go to the person's profile and look for their Story Highlights. If the highlights are missing, it could indicate that they have hidden their Stories from you.

  2. Use a Different Account: Log into a different Instagram account, either your own secondary account or a friend's account, and check if you can see the person's Story. If you can't, it's likely that they've hidden their Story from you.

  3. Ask a Friend: If you have a mutual friend, ask them if they can see the person's Story. If they can, but you can't, then the person has likely hidden their Story from you.

  4. Private Account: If the person has a private account and you're not following them, request to follow them. If they approve your request and you can then see their Story, they probably didn't hide it from you.

Please note that if the person has limited their Story to Close Friends, you won't be able to see it unless you're on their Close Friends list.

Remember that these methods won't work if the person has blocked you on Instagram, as you won't be able to access their profile or see their Story in that case.
