Meta has agreed to strengthen its age estimates to keep kids under 13 off its platforms and teens in age-appropriate accounts, enact a hard limit of two hours a day for users under 18, block kids from the apps from midnight to 6 a.m., and hide "like" counts, among other changes.

Meta has agreed to pay $17 billion and add stronger child-safety measures to its Facebook and Instagram platforms to end a landmark trial over teen social media addiction and settle claims filed by 47 states, state attorneys general announced Wednesday.
