played this game for years but I deleted the game due to a texture pack issue after that, i installed minecraft again. I pressed the sign in button and it took me to the sign in page, but I could not see anything either then a white screen and the word "sign in" at the top of the screen, after a few seconds it restarted the game and redirected me to the starting page,I consistently pressed the sign in button and the same thing would happen over and over again until minecraft said that I can't use the marketplace and realms. They addressed the bug as crossbow.
