Mark, with credit card being my only access to Qobuz high res, I'm really wanting to find an answer also. I continue to get generic email from Sebastien saying Qobuz has new music. Which is like a kick in the nads. Kinda makes me angry. I emailed the "customer service" in a check out page because I wanted to make sure everyone that could, knew I was having problems paying and just like I suspected, the next day I receive a reply to that email from... Sebastien.
The amount of time it takes to solve this CC issue, is time from my yearly subscription. When all gets straitened, I hope that's also in the Qobuz mind. Mark, I'll go through the check out process and compare, tomorrow. I think your getting closer than I am to making music yours.
