The problem has returned: some tracks just do not play (they are skipped).
Example: the first track on Aja in high definition, but htere are others.
With Aurender’s Conductor app no problem playing Aja Qobuz 24/96 (Netherlands)
No problems from the UK either (Aja 24/96 via Mosaic or Connect).
It looks like it may be a local issue for you wherever it is that you are situated. I assume that it isn’t Netherlands or UK. Qobuz has a different service for each territory that it serves.
When this was happening earlier in the year it seems ihat ti was caused by Qobuz making technical changes with its distribution. With 100,000,000 tracks claimed I guess this was ( is ?) not an overnight exercise. I suggest that you leave it a few days and see if by then if it has sorted itself out.
