OOn happn, it's not possible to unblock a user once you've blocked them. This measure is in place to ensure everyone's safety and privacy. Blocking someone is a permanent action to maintain a respectful environment on the app.

If you really want to reconnect with someone you blocked, you can delete your account and create a new one. This way, you'll have a chance to cross paths with that person again. Just remember that you'll lose all your current information and Crushes, so think carefully before making this decision.
