The AION 2 team has acknowledged an account-linking error that may prevent players from logging in, with the issue potentially affecting only Steam users. Its official notice on Steam provides a workaround for affected players: restart the Steam client to enter the game.
That advice is for players having trouble getting in. For those already logged into AION 2 who want to remain connected, the team recommends not logging out. The practical response therefore depends on whether players are currently blocked at login or already playing.
The notice also addresses consent relating to Throne and Liberty. The team says players who agree to the Throne and Liberty terms and data-collection terms will be able to play AION 2 normally. That is a separate point from the Steam restart workaround: the notice covers both access through the client and the consent terms associated with normal play.
The team is working to remove the Throne and Liberty consent prompt. It says it will update the same notice when the prompt has been removed and when it has more information, making that announcement the place to follow progress on the change.
