I downloaded a game recently but now it's according to my Xbox never been installed this game ...

Rainbow Six Siege was free to play for the past weekend. It was only available for that free period once that has finished you would need to purchase it

Starting August 16 until August 20, 2018, Xbox Live Gold and Silver subscribers will be able to play
Rainbow Six Siege free on Xbox One all weekend long.

Thank you for helping me understand what happened.

No, it's not the router as I explicitly explained in my original post. I download games off of steam on my pc using THE SAME router on THE SAME network and there is no comparison. a 30 gig game on my pc, just under an hour, 30 gig game on xbone? 3 DAYS!!!
I started downloading the newest Naruto game an hour ago at the same time as my fiance on her xbone on a different network. Hers is finished, mine is at 2%. This has to be xbox, there is no other explanation. Not when the only console affected is the xbox
one itself. My tablet, my computer even my phone all download files quickly, as quick as my internet speed allows. But the xbox? no, I mean no one can argue that 3 days for a game install is just blatantly and aggressively illegal. I am paying for a service
and microsoft is not providing that service, that IS stealing. I don't need a technical fix or a suggestion, what I really need now is someone to provide me with a lawyer who will take a case wherein the terms of a legal contract (between myself and microsoft)
are being and have been being violated. I mean at the time of my writing this I have been downloading a game that should, according to my isp and speed tests, according even to microsoft by it's handy dandy little cheat sheet/graph ,should have been downloaded
and installed by now. According to math, something I am good at, I should be playing this right now. But I am not irritated that it's been an hour, I am irritated that it's going to take another TWO DAYS! It's not a technical issue any more, if it ever was,
it' a legal issue. I'm just sick of paying and paying for a service, for games, that should be a source of fun and relaxation instead being a source of constant, consistent irritation.

According to my fiancee the game isnt appearing in the ready to install and the xbox its self has been reset. The game says purchase in the store, but says purchase and install on my phone ( since thats where I pre ordered it from about 5 hours ago.) Once
I click install from my phone it says attempting to install, we will push the content to your home console.... Also the xbox is on which means once the said issue was fixed it should begin downloading, but it has been hours.

I've just recently installed walking dead season three. It has been purchased and downloaded.

It is in my 'recently installed' list which is in the same thread as the 'Que' icon. ( hope this makes sense). However the game does not show available in my 'games' list. I have tried installing it via my laptop, and it recommends i do this...

"We'll try to push-to-install this on your home Xbox One. If you’ve blocked automated downloads, you might want to enable them. On your Xbox One, go to Settings > System > Updates > Keep my games & apps up to date. By the way, you can find this and anything
else you’ve installed in My games and apps."

My xbox is already on the automated system to install downloads, i haven't had any other problems with downloading games and installing them apart from this one... any help or advice will be much appreciated.
