Came to this topic by googling this issue.
Few days ago I bough this game in a computer shop for Xbox (Xbox Series X).
I'm experiencing exactly the same issue as the other users. I'm gaming on a 4K TV and I succeeded to open that login page (Connect me now) only when I connected to my Xbox remotely. So I believe it could be related to rendering screen resolution (my laptop has FullHD resolution). I've typed in the credentials but nothing happens.
I'm attaching the screenshot. The second time I tried to open the login page doesn't work.
Please let me know what other technical info should I provide to solve this issue fast.
