It seems to be coinciding with the launch of the new law of the social media ban for under 16's in Australia, which officially started yesterday, and for which other sites, like Meta, have been implementing things for a couple of weeks already. The Sims 3 website has a link to-sign into-share on Facebook feature, which is also in the game so I don't know how it would effect that, just be an empty button I suppose. You might find that there are interruptions on the Sims Discord thing as well.
People not having any trouble are probably ... not as young. Somewhat older.
Here are the social media links down the bottom of the page
And the share-to-Facebook buttons in the studio memories that used to be there ... are gone now.
This used to have a Facebook icon for sharing each memory in my studio
Clicking on the links down the bottom of the page under 'Stay in the Loop' these days takes you to either The Sims official You Tube Channel, now banned to under 16s in Australia, and to the Sims official Facebook page, also banned to under 16s in Australia now. Twitter, now X I don't have and its reported on the news its not clear what's happening with it.
My guess is the maintenance has been about that, and the long time active accounts obviously older are probably the one's not having problems
i'd have to say your conjecture about access and ages isn't accurate. i had as much trouble as anyone else, i started my sims3 account in 2010 and it's been active since then, and am definitely way outside the age range that the media ban is targeting
