they are working on it… as of today, most people are able to enter the game (bugs inside the game are another story)
but granted, yes, some folks are still locked outside and still cant load the sim
they think they have traced it to 2020 incompatible addons which they will disable shortly (maybe they already did) to rule out that problem
if you were not a user of 2020, so, your 2020 addons are non existant, and you still can’t load the sim, its possible something else is happening here
