Hi there! Thanks for reaching out. Checking your account in our system, we can confirm your Steam account is [b]not[/b] part of your existing Cross Save setup, which explains why you don't see your Xbox characters when logging in on Steam. This normally means that the fix would be to add your Steam account to your existing Cross Save setup. However, as you mentioned that your Steam account appears to already be linked on your end, then this means something has gone awry in the Cross Save process. In this case, the only fix is to disable Cross Save, wait out the mandatory cooldown for doing so plus any cooldowns for recent purchases, then set up Cross Save anew, this time making sure to select and configure all desired platform accounts at once. That said, while you wait out the cooldowns during the time Cross Save is disabled, your characters will still be available to you, but only on their original platforms. Also, please note these cooldowns cannot be expedited or removed under any circumstances, with no exceptions.
