There are a few ways to view Instagram Stories anonymously. Here are three of them:
Use a third-party app. There are a number of third-party apps that allow you to view Instagram Stories anonymously. One popular option is StorySaver. To use StorySaver, simply install the app and search for the user whose stories you want to view. The app will then show you a list of their stories, which you can view without them knowing.
Use a web browser. You can also view Instagram Stories anonymously by using a web browser. To do this, go to the Instagram website and log in to your account. Then, click on the profile of the user whose stories you want to view. Their stories will be displayed in a slideshow format. To view a story, simply click on it.
Turn on airplane mode. If you only want to view one story, you can turn on airplane mode on your phone before opening Instagram. This will prevent Instagram from sending a notification to the user that you have viewed their story. Once you have viewed the story, you can turn off airplane mode.
Please note that these methods may not work all the time. Instagram is constantly updating its features, so it is possible that these methods will become obsolete in the future.
