My son uses an iPhone XS running iOS 18.7.2. He is able to bypass all Screen Time app limits by manually changing the date under Settings → General → Date & Time. When he sets the date/time forward or backward, the configured Screen Time restrictions no longer apply.
Please make it possible on iOS 18.7.2 (and future versions) to prevent manual date and time changes when Screen Time is enabled, so that children cannot use this method to circumvent app limits.
Thanks for the post.

As a parent like you I believe parent/guardian, you can prevent this loophole by locking the date/time settings within Screen Time. As a parent I would recommend to lock all the settings.
You'll find better help on ScreenTime in the link provided and they'll be able to help you better than in the developer forums.
