I have experienced a consistent bug with screen time in IOS 18 DB1. It just doesn’t work, but the limits still function. I cannot access screen time settings (it just crashes) nor can I disable screen time from within a blocked app itself. Have not found any workaround.
I have logged a feedback report, FB13932765 (Unable to open screen time settings, it just crashes)
I Hope this can be looked at and resolved by the next update.
Thanks, Felix
