Well the thing is that i press sign in and have everything typed in but then it still says sign in but now i can't press it and that means i can't access my profile from the top right which then means i can't access any settings. It's super weird. Btw
i can't even sign in at all at the enforcement page it just refreshes the site.

Im trying to login in on my switch (the console i play on) i used my tablet to login my switch when i get done with the code and stuff it sends me to a website name "sisu.xboxlive.com" and it says "sisu.xboxlive.com is currently unable to handle this request."

The URL is right, i just can't use it :\ It's always the same error ''Unknown Gift Code''. I'm a bit sad about it because i use discord a lot.

I can't even sign into my profile offline. When i try to sign in i am requested to give my email. It then errors and says to try again later and does not let my profile stay signed in offline. Therefore I can't access any saved games.
