same here, swiss as well and there are only german audiobooks for me. I can't even find english audiobooks, even though I am specifically looking for the english name ('me befor you' instead of 'ein ganzes halbes jahr')
I also have this issue. I'm glad to see that you have added audiobooks to Spotify, however, I am not interested to listening to audiobooks in German simply because my bank is located there.. There is no reason why I shouldn't be able to listen to an English audiobook from a German speaking region. I can buy English books in German speaking regions, as well as listen to English music.
