If your Qobuz app on your new iPhone is only playing 30-second samples, even though you have a valid yearly subscription, it might be due to an account or app issue. Here are some steps you can try:
1. Verify Subscription: Ensure your subscription is active by checking your account status on Qobuz’s website.
2. Log Out and In: Try logging out of the Qobuz app and logging back in. AND, if needed, as noted above, Delete the Qobuz App and reinstall it.
3. Clear Cache: Clear the app’s cache if possible, as cache issues can cause playback problems. Also power down your iPhone completely, wait 2 minutes and restart it.
4. Contact QoBuz Support: You can reach Qobuz support via email at support-help@qobuz.com.
I hope this helps.
