I was finally able to login to the Qobuz app again, but not through Sense. I had to uninstall Sense, access the Zen Mini via web (my.innos.com) and was able to log in to Qobuz again. I then reinstalled Sense, 30 mins to re-update my Qobuz library and good to go.
Such a relief, I thought I would be without Qobuz for mine and Mrs Painter's Friday booze and Jazz evening 🥳🥳🥳
