Not just fjordur, its doing it to me now on rag also. I can randomly get logged in one try in 20?-50? and then the game plays fine. Almost every time it loads all the way and then dashboard. Does this on two xboxs in my house, a one x and series S, and to my tribemate on his series x at his house. Took him three tries.
Now it shows 1 player logged in and when I go to log again it says player with this account already logged in.
I think crediting a few days to my servers as basically being unusable is not unreasonable between the charcar update and whenever this is squared away. Single player works on all maps.
