I was playing DnD with some of my firends when I was randomly logged out of my DnD beyond account. I didn't think much of it and signed back in, but when I did, all of my campaigns, characters, and everything I had saved was gone. The DM was still able to see my character and information, and it still showed it was associated with my account for all the other members of the campaign, but I cannot find a way to get all the information on my account back. I tried waiting a week to see if it would fix itself and logging into my account on another laptop, but nothing has helped.

According to your account it’s brand new. Did you accidentally log in u der a different account?

One of them might be Apple, the other might be Google or Wizards or something.
