One More Minute is disabling Screen Time

As per the title.

I’ve been having a problem with my children’s devices since installing the iOS 16 and iPadOS 16 update. Where previously the devices would lock at the Downtime times set in the Screen Time settings app, now they can continue unlocked through the night.

There was always the ability to tap the One More Minute button to give themselves time to leave a game, or finish watching a video and I could always enter my passcode and give them an extra 15 minutes at the weekend. If I’m already there before their Downtime allowance runs out, I can enter the passcode and they get the exact time extension that I give them and the devices lock at the new time as expected.

Ive found what breaks it though: it’s that One More Minute option. If it gets tapped, then Screen Time gets turned off everywhere. On my iPad, in the screen time settings for their account, Downtime is now off. The Scheduled and Block at Downtime sliders are both off. All the Content and Privacy settings get reset to default.

If I toggle the Scheduled slider button back to On, then my iPad suddenly remembers that the children’s accounts are supposed to be off at this time of night and it immediately locks them all, but it still shows the default lockdown time of 10pm. After a few moments the settings all reload and show the times and Content settings that I’d set the day before appear in there.

This is repeatable and recurs nightly if and only when that One More Minute button gets tapped.

All the devices, including my own are on iOS16.2 and iPadOS 16.2.

I’ve previously shut them all down and disabled Screen Time from my own iPad before running through the Screen Time setup from fresh, as iOS 16 introduced new options in that setup that some people think are the reasons for Downtime breaking, but it did not fix the issue for me. It is definitely narrowed down to One More Minute.
