I am having the same issue. I am also having an issue with which version fo the game I purchased. I purchased the Hero Pass and I can only download Windows 10 Edition. I do have the ability to update to the hero pass as the website tells me I should have the option to do. I was able to play the game about 5 hours ago this afternoon but now I can not sign in on any of my PCs. It claims here that this issue has been resolved but I am still having the issue so it has not been 100% fixed yet.
