The XBox One is an absolute disaster area when it comes to multi-region support. The single most annoying example is that the interface language is linked to the country you're in. For example, living in France, with a French credit card, I can't configure my XBox in ENglish if I want to be able to buy things. I can lie to my XBox and tell it I'm in Australia after having purchased things though, and it will then let me play my games in English, but I will have to switch everything back to French if I want to buy something else.
