I have issues accessing Nintendo EShop, once i try it gives error code 022-2502 and says "This Nintendo Network ID cannot be used because its region setting does not match the setting of this system" I've scoured youtube but only one person has details but i have to wipe my system clean.
Switching back to your initial region helped your current case, but I still suggest updating the information if it's incorrect (I'm not entirely sure if you're actually located in the US or on Anguilla), as this might prevent more/other problems in the future.
Guides to do so are available on nintendo.com:
- for your Nintendo Account Profile, and
- for the Nintendo Network ID you might have created when getting your console.
Both guides mention that what might be preventing you from changing your region is still having credit on your account. Spending it should fix that problem.
