How to read Instagram messages so that a person does not find out about it

If you don't want your interlocutor to see the status "Viewed" under the message, then this feature is for you:
1. Go to the application settings.
2. Open the "Privacy" section.
3. Scroll down and select "Accounts with restricted access".
4. Click "Continue".
5. In the search field, enter the login of the account whose messages we want to read in secret.
6. Click on the "Restrict access" button.

Done! Now the person will not know that you have read his message.
