that is super weird that you never entered the name john gaming! my only guess is that Godot must have given you and another person the same device ID. i’ll have to look into it, maybe for whatever reason multiple people got an empty ID or something and that’s why.
if you linked the other account, and it’s someone else’s account, they can still submit scores as you, but they won’t be able to do anything else if you own the parent account.
i’ll look into it. thanks again for the bug report!
