I have an old account on Spotify that I created when I lived in the US (I can't even detach it from Facebook). Now I'm back to Brazil and I made an upgraded to a Family Plan. I need to change my zip code because I'm not being able to add anyone to my account because zip code is not matching with my brazilian one. There are 3 others using it, but I'm not being able to add one more. And I don't know why.
When I go to Edit Profile menu, I'm able to change my phone, carrier, but the zip code option is not there for me, as shown on the image.
