Today, Apple has released iOS 13.3.1 and iPadOS 13.3.1 beta 1 which alongside the normal bug fixes, we expect it to patch an exploit for Screen Time Communication Limit.
The release notes for the update are completely empty.
The exploit allowed children to bypass through any restrictions put in place by the new feature by allowing children to add a new number to contacts, and then proceed to text or call them.
In a statement to CNBC, Apple confirmed they were working to fix it and today they have.
