I'm sorry to hear that you can't see your heroes and content currently! I've seen some other reports of this today, and the issues were temporary, so I don't think you should be worried. I checked your account, and I only see PC and one session on PS4.
Did you mean to click Xbox for the tag on this thread? If not and you are discussing your PC copy, I see you as level 24 on our end. Restart your PC and let me know if the issue persists!
If you did mean Xbox, please send me your gamertag in a PM.
