eventDeviceActivityThreshold from DeviceActivity will fire early and block apps after downloading iOS 26.2

A screen time app I'm making has started telling users that their limit was reached even when they're far below their limit for the day (sometimes even at 0 minutes for the day).

This issue only started happening after upgrading my software to iOS 26.2.

Is this happening to anyone else? If so how have you found any solutions or does anyone know of any changes that could be causing this? Any help would be appreciated.

Hello,

we have reported this concerning bug with the first beta of iOS 26 in June 2025.

Apple has not yet addressed this bug, neither do they have acknowledged that anyone has taken a look at it.

I believe this is yet another confirmation that Apple is not interested in maintaining the Screen Time framework – it’s now in a state where it’s barely usable to build stable apps.

here are my feedback number for reference:

feel free to cross reference those in your feedback reports!
