Typically the 30 second playing means there is a log on problem with your account. Are you using the app or the web.
I would delete any instances of Qobuz and reinstall... or log on the the web browser version.
Qobuz will not work with new iphone
I just got a new iphone and my Qobuz will not play any music more than 30 seconds. I have a yearly subscription and it is in good standing. I logged out on my old phone and logged in on the new phone but still nothing. I can't find a place to get support from Qobuz. Need help please. Thank you!
