Open Slow Time Club and wait a few seconds on the Home screen. It checks every block and removes any that have finished.
Check nothing else is blocking the app
Another block. A Focus Session or Quick Block may cover the same app. The Home screen in Slow Time Club shows what's running.
An App Limit. If the block screen says That's it for today, the app has used up its time for today. It unlocks at midnight. See App Limits: how do I set a daily time budget for an app?
Something that isn't us. A grey screen with an hourglass usually comes from Apple's own Screen Time limits or another blocker app. Our block screen is dark and mentions Slow Time Club. See Another screen-time app, or Apple's Downtime, is interfering.
If it's still blocked
Restart your iPhone.
If no Quick Block is running, start a short Soft Quick Block that includes the stuck app. Then tap STOP and Delete block. This makes iPhone rebuild its list of blocked apps from scratch.
If you contact us, tell us which kind of block it was and roughly when it should have ended.
Why this happens
Sorry about this. Ending a block works the same way as starting one: iPhone has to wake Slow Time Club at the end time, and sometimes it does that late. Now and then iPhone also keeps showing a block screen after it's been told to remove it. Opening Slow Time Club or restarting your phone usually clears it.
