This popped up when I opened The Sims 4.

Hello, I opened up the sims this afternoon and this was on my screen. There was no other information available, and I am concerned about what exactly this means. Any information would be greatly appreciated. I did not have anything other than Origin and The Sims 4 open on my computer.

The text reads:
CHILD ACCOUNTS CAN GET THIS
This is a message that should go to everyone, INCLUDING (but not targeted exclusively at) child accounts.
