Xbox Game Pass Country restriction

If the country is not listed there, then it's not supported. Estonia is not supported by Xbox.

Game Pass isn't exclusive to the US. I'm in Canada, and I have it.

"An active Game Pass subscription is required to play games. Some games may be available only to account holders 18 years and older. Games and the number of games offered may vary over time and by country/region, and may not be available in all locales."

It literally says in the description that it is avaible for Norway, but it forces to switch to US? it dosen't really make sense, Im not really restricted by whats offered to me, Im restricted by what country the gamepass only allows me to choose in payment

There's no word on if/when Game Pass will expand to other countries. Use of a VPN or anything else to bypass region restrictions violates the terms of service and would put you at risk for being banned.

The link below is a list of countries where Xbox Live is available. Even though you redeemed the code in the states, the game may not be available in your region now either due to restrictions or if the country you are in is not an xbox live available country.

Sorry but this is not the fault of xbox. Restrictions imposed by a country's government are what is responsible for some games and/or DLC not being available.
