Learn about if and when Instagram notifies someone when you screenshot a post.
In this video, I walk you through the steps of screenshotting one of my accounts and then switching over to it to see if there's any sort of notification. The quick answer is no, Instagram still doesn't notify the person if you screenshot their post (video or photo) in 2022. It also doesn't notify the person if you take a screenshot while viewing their story, IGTV, or reel. These all are ok to screenshot or record and they won't ever be notified.
There is one exception to this rule. If you screenshot a photo or video that was sent to you in DMs then Instagram will notify the person you took a screenshot. So make sure you don't screenshot anything in the messages unless you want them notified.
I hope this video helped solve your problem. App still not working? If so, drop your question in a comment below!
