Check that Screen Time permission is granted (Hurdle → Settings), the hurdle is enabled, and give iOS up to a minute to apply a new shield. A restart of the app after first granting permission can help.
Unlocks apply within a few seconds. If a shield lingers, close and reopen the locked app. If several hurdles cover the same app, every one of them must be cleared.
Usage data renders on-device only and can take a few seconds to appear. It begins collecting after your first hurdle is created.
Deleting Hurdle removes all of its locks immediately. We hope you won't — but it's your phone.
