Instagram doesn't notify you directly if someone screen records your story. So, no, you can't really see if someone has screen - recorded it in a straightforward way.
Well, it depends. Instagram has certain privacy features for story creators. If they have toggled on the option to be alerted about screen recordings, then they can see that someone has screen recorded their story. But if they haven't enabled this, then no one will be able to tell that you've screen recorded it. So, it's not an automatic thing that everyone can see for every Insta story.
Instagram doesn't have a built - in feature that alerts users when someone screenshots their stories. However, there are some third - party apps that claim to be able to detect screenshots, but these are not endorsed by Instagram and may not be reliable or could even violate Instagram's terms of use. So, typically, the answer is no, no one can see if you screenshot an Insta story.
Yes, Instagram can potentially notify the person who posted the story if you take a screenshot. However, this feature is not always reliable and may not work in all cases.
Yes, Instagram doesn't currently notify users directly when you replay their story, but there are some indirect ways they might suspect. For example, if you are the only one who views their story multiple times and they notice an increase in views from your account each time they post a new story, they could potentially suspect that you are replaying. However, there is no official 'replay notification' feature on Instagram.
