The Call of Duty Black Ops 3 beta had a less than stellar start on the Xbox One yesterday.
Many users reported beta codes not working, the Paint Shop wasn’t loading, and even game crashes.
Fortunately, the code issue has been fixed now. But, no word of yet on the crashing and Paint Shop issues, though Treyarch is aware of the issues and working on them.
There is a work around for the Paint Shop problems, where if the menu does not load, you can switch on the “See content that other people make” option in the Xbox Privacy menu.
Hopefully the problems will be fixed before the open beta tomorrow.
