Currently, there are no confirmed symptoms of Qobuz account being unable to log in.
Does your account log out of your Qobuz account at some point after logging in? If so, the issue has been identified and is currently being fixed.
If you can't log in to my Qobuz account, can you log in to Qobuz's own app?
Since the recent software update, the Qobus login on the Rose device does not work anymore. Please fix asap!
