This function comes into effect from last few days only. We confirmed it at our end. In previously result, it shows star icon with the name of the user. Star icon indicated that this user takes the screenshot of this story. Instagram app new update no longer support this function.
The previous feature was helpful for those who want to know who took the screenshot of their stories. Now, the star icon place is coming empty even after taking the screenshot of the story.
Instagram team remove this function to make easy use of Instagram for its user without taking any extra effect. Instagram officially did not say anything about this change. We always love to take screenshots without coming into anyone eye.
Now, no more risk in taking screenshots on Instagram, go wild with it.
