I just wanted to find out why for the last 3 months I have been charged an international transaction for my monthly subscription. Instead of being charged $17.99 I am now being charged $18.54 and it's showing up as GBR. Not sure why this has changed in the last 3 months. It used to show as Spotify Premium AUS. My country is set as AUS so why am i now being charged GBR??? How do I solve this issue?
