Yes, in Snapchat, you can view some old Snap Stories depending on the settings. If the story creator has set their story to be available for replay within 24 hours, you can see it during that time. But once the time limit expires, usually it's not possible to view it directly from the app.
Yes, it is possible in some cases. If the story was saved to your memories, you can view it. Also, if the sender allowed for replays and the time limit for that has not expired, you can see it again.
To see old snap stories, start with your Snapchat memories. Snapchat sometimes saves stories there, especially if you've enabled the feature to save them. If it's a story from a friend, and they have the option for replays enabled, you can simply go back to the chat where they sent the story and look for the replay option. However, keep in mind that not all stories are available for long - term viewing. Some are designed to be short - lived and disappear after a set period. So it really depends on the settings of the story creator and your own Snapchat settings for saving and viewing content.
As I said before, if the sender saved the story in their Memories and is willing to share it again, that's one way. Another thing could be if the sender had taken a screenshot of the story while it was live. They could then show you that screenshot which is like a form of seeing the old story.
As of now, no. Snapchat doesn't provide a feature that allows users to see who has watched their Snap Stories. This is different from some other social media platforms. It gives users the freedom to view stories without the worry of being detected, which is one of the reasons why Snapchat has its own charm and a large user base who like this kind of privacy.
As of now, Snapchat is designed in such a way that it doesn't let the story creator know if their story has been replayed. So, no one can see if you replay a Snap story. This is different from some other features like when you take a screenshot of a Snap, which can be detected in some cases. But for replays, it remains private.
No, Snapchat does not notify the person who posted the story if you take a screenshot of it. So generally, people can't see if you screenshot their Snap stories.
