My Question or Issue

Recently tried to upgrade to Spotify Premium. Changed region from US to UK and when I go to purchase a premium membership it is in USD and asks for billing information for a US address (US states and ZIP code) rather than a UK address. Wondering how I can update the billing info as I already changed my region from US to UK a couple days ago. Tried looking at guides on how to update them but they are in 2016 or I just generally cant find them such as an update billing button.

Edit: 

I have read the article on "Updating Payment Details" and couldn't find the UPDATE button under Your Plans.

Edit 2:

Turns out I had to change regions in the url from /us/ to /uk/ and problem solved.
