I am trying to invite my girlfriend to Spotify Premium Duo. We are living in Australia but due to the Credit Card I'm using for Spotify is issued from Singapore, I had to update my country to Singapore as otherwise it would not allow me to use that card.
In the Spotify Duo invite i have added our Australian address but when she is trying to register using the invite link using our Australian address, she is getting an error that we are not living in the same country. Also, I'm not able to edit her country setting to Singapore unfortunately...
How can I get her onto my Premium Duo account?
