23 hour screen time block doesn’t take effect

If I create a block lasting 22 hours it works as expected, but a block lasting 23 hours doesn’t work.

I understand this may be a screen time issue, but even if it is it would be helpful for One Sec to warn you if a block may not take effect.

For a strict block it is impossible to retry with a shorter timeframe - my ploy workaround was to uninstall and reinstall the app.

I can reproduce this consistently with a block lasting exactly 23 hours.
