The Divison 2 Installation Stopped

So I purchased the divison 2 on Friday night and it's now Monday morning and I still have not been able to install the game. Initially I thought it was a storage issue as I had just enough space for the install from the disc and then the update, but even
after deleting some old games (ensuring more than adequate storage space), this doesn't seem to be the issue.

The game installs from the disc just fine (I've done this 'offline' as well to see if it made a difference), however it's when incoke to install the update that I run into issues. The update is approx 55GB and each time I've tried to install it gets to 53.14GB
(96.7%) and then the installation stops. No error or reason is given, it just stops.

So far I have tried the following 'fixes':

-install game offline, then go online to install update.

-clear local games and restart

-power cycle (unplug xbox for 1min)

-uninstall game, reset xbox, reinstall game from disc offline, update when online

None of the above have worked. All my other xbox live features work, my connection is fine and I can download other updates for other games/apps. This is just super frustrating because it takes about 3 hours to download the update up to 53.14GB each time
before it fails!

Any advice would be appreciated!

Thanks
