Changing country region
Good day please help me on how to fix this stuff.
my Apple location/region is in Nigeria . I got an iTunes card and want to redeem it to my App Store account so from the instructions there I had to cancel all current subscriptions and change my country region to US because The ITunes card was bought there. But my challenge now is that it’s not working yet and I can’t still redeem the card. The region keep changing to Nigeria. I really need to see that my App Store is working and I can pay for subscriptions through it.
Please help me, I await for your good response .
thanks
