Yeah I have tried multiple browsers and I still get the error. Oh well.
Must seem like its over then.
I’ll update the post now so everyone knows anyway. 
I just did it right now and it worked for me 
I downloaded the thing about 2 days ago and it’s not come up how will I know when I’ll get it?
I clicked the source link and it didn’t work but when I searched xbox ie on facebook it worked then. I did it this morning, it said I had to wait 1-2 business days but I got the update today.
Well it wasn’t even out 2 days ago you derp.
If it’s not out now it’ll be coming out.
Just did it and just waiting for the update to happen to me now;O
Got it yeah!
Mine has just came, as of 23:23PM (UK Time)
So you guys in the UK & Canada should be getting yours pretty soon.
