The new restrictions for teen users are gradually rolling out starting Tuesday and will be fully implemented by the end of the year, Meta said.

Last year, Instagram began putting all users under 18 into teen accounts, applying its existing restrictions on kids under 16 to a larger swath of young users. Teen accounts are private by default and come with safety features that silence notifications from 10PM to 7AM as well as block DMs from strangers.

Teens under 18 will feel the effects of new controls by the end of the year, and they need a parent's permission to opt out.

Removing teen accounts from YouTube won’t improve online safety, the video streaming platform told a parliamentary inquiry. Rachel Lord, public policy senior manager, Google and YouTube Australia, appeared today before the Senate Environment and Communications References Committee on the Social Media Ban.
