My country of residence is one different from the actual one in My WiiU console. I know from previous experience that NNIDs are disabled if it’s country of residence is different from the console. I know, also, that PNIDs don’t react this way as I’ve changed it’s country in the Account’s settings.
Knowing this, it means changing the console’s country of residence is safe with PNIDs and won’t ruin anything with any of the services, right?
