Cant really comment as I do not stream with Qobuz from AS. I have a sublime subscription which I use on the Qobuz app on my ipad to to discover new music which I purchase and install in my local library. Qobuz is connected to AS for the album reviews and artists bios only.
This thread has some information Qobuz "Error loading track" on first tracks of many albums - #10 by Jud . Would also suggest you look at the hundreds of posts on the Roon forum from users with similar issues to yours and see if they match your experience.
