Thanks for the info, BorisM.
You’re welcome. For now, any given track may or may not work at any given time. It might work later though. Or th one that worked before might not work 
I have experienced the same issues on my rs130 transport lately. Many songs from Qobuz can not be played. I updated Qobuz and rose connect app. Installed them new on my phone and tablet. I log out from qobuz on my rs130 and logt in again. I updated time and zone on RS130. No results. I have pending a factory reset. But reading the comments it seems yhat the issue is more on Qobuz side?
We are also continuously investigating the issue where Qobuz tracks cannot be played or are being skipped.
We will do our best to resolve this as quickly as possible.
We apologize for the inconvenience.
Up to you, of course, but I found a factory reset made no difference. The good news is that the problem appears to be clearing up. I’ve seen a reduction of about 65% in “cannot play” errors over the last ten days, with several albums playing without error. It appears that Qobuz and/or Rose are making progress.
@Serge
Upon checking today, I found that most of the tracks that wouldn’t play until yesterday are now working properly. It seems there was some maintenance or an update on Qobuz’s end, as described below.
That’s exactly what I was trying to convey. The problem is at Qobuz end. You probably intended to tag @Alberto
