Hi Everyone,
I spoke with several tech agents yesterday through the online support. The last tech rep said that the Sims 3 support team is aware of the 'login loop' issue with the website and are looking into it as well as doing a major upgrade to the page. It may take some time for them to get things worked out but at least in the meantime most are still able to play the game. Until then I would suggest saving CAS creations and lots to the game bins until they are able to be shared.
For those of you who don't have all of the worlds, many of them are available in the EA app so the new purchases can be added that way. Since I own all of the worlds, the access codes for them won't work in EA so will have to wait until the website is fixed to get the rest of my store items and worlds for future use in game.
So far although I'm not able to sign into the website or the game launcher, the game logs me in once the game loads.
Until these issues are fixed as well as those for Sims 4 players I hope you all still have fun with your sims and have a wonderful Holiday Season!
