COD stuck and not loading.

Yup, been running into this problem. I'm trying a reinstall but I am not that optimistic about it.

I've had this problem off & on for a couple months now but today it stayed "stuck!" so doing the reinstall thing but can't figure out why only this game? all other games no probs. so much for all the greatness with this new console. find myself playing the
360 more & more

Another way to fix the issue is to hold down the power button on your Xbox One for a few minutes, until the power brick turns orange, and then turning it back on.

i had same issue but made it worse when activison told me to uninstall all and when you do you will not be able to download season pass again mine glitched and microsoft cant work on it till next week oh and they also had me buy the hardend edition and the
season pass still wont download now i have 2 digital copies of ghosts but not my season pass or dlc

There's a lot of problems like this that I've encountered. I'm sure they'll get it all together eventually, but it's a really gradual process I'd imagine. Hopefully they'll fix all these problems before all the big games come out!
