Hi @peter 🙂 I think this is because Facebook made “Strict Mode for Redirect URI’s” required for all Facebook apps ([Stack Overflow thread here](https://stackoverflow.com/questions/49412342/how-to-turn-off-use-strict-mode-for-redirect-uris-in-facebook-app)). I solved the error in an app by copy+pasting the exact Bubble URLs (that a User can be directed to when logging in with Facebook) into the “Valid OAuth Redirect URIs” section in Facebook. This thread contains a screenshot on where to paste the URL as well:
