Having the same problem. I entered my address haphazardly because, like many addresses in Panama, they are more complicated and more like guidelines. Now I can't add my wife because I didn't realize how important it would be at the time to record EXACTLY what I entered.
Well, this is very annoying. I don't remember what exactly I wrote as address and I can't look it up. And the spotify support also can't look it up for me. They offer me to create a new account and cancel my current subscription. And they would manually move my playlists to the new account. Now, how absurd is it, to force my to waste my time and your staffs time by making them deal with manual work ?
This is just plain stupid that you can't view your address and you have to delete your entire account and contact support anytime you move... was going to get if for my family but nevermind, guess I'll stick to Google Play where its so much less restrictive.
This is really dissapointing. I have been a long time user of Spotify Premium and not being able to use the "family" subscription and share my account with my children just because I don't remember the exact address I wrote when I first subscribed months ago is simply RIDICULOUS!!
I am considering leaving Spotify to Google or Apple music. Hope to find a solution soon, otherwise I will be shutting down my account.
