Did I accidentally swipe left on someone in Facebook Dating, and can I undo it?

If you've accidentally swiped left on someone in Facebook Dating, it's important to know that the app doesn't have a standard "undo" feature like some other dating apps. Once you swipe left on a profile, that action is typically considered final and the profile will not reappear in your match suggestions. However, since the app may cycle through profiles after a certain period of time or under certain circumstances, there is a chance you could see the same person again in the future. If you're interested in someone you've mistakenly swiped left on, your best bet is to keep an eye out for their profile to show up again in your suggested matches.
