Just had this reply from Qobuz…
Dear customer,
Qobuz has launched the Studio Premier subscription in the United States for $14.99*.
This subscription is not yet available for other countries in which Qobuz operates.
This is a temporary situation, due to the ongoing negotiations with publishers in other countries.
Qobuz is working to harmonise its subscriptions and Studio Premier will be available in your country very soon.
Thank you for your confidence.
Best regards
