As requested by some users: ‘old’ style now accessible via https://old.lemmy.world
Code can be found here: https://github.com/rystaf/mlmym , created by Ryan (Is he here?) (Yes he appears to be! @[email protected] ! Thanks for this awesome front-end!)
I saw the same thing. The issue is you are not automatically logged in to old.lemmy.world just because you are logged in to lemmy.world.
