Hi,
I have a main and alt on the same account, and both located in Exodus. I can login on my alt, but not on my main. That makes absolutely zero sense.
I can see this is an issue affecting many people for roughly the last five to six hours. Where is the response from SquareEnix? At least a confirmation that you're aware of the issue, and working to resolve it? I like to just login around this time and flip my retainers before I go to work, but for some folks, this is prime play time they're losing out on. Basic customer service is at least letting your customers know that you're aware of their problem and working on it...
