Qobuz’s answer:
We have encountered some one-off problems that match your description, but we do not know if it is a problem with Roon or an external infrastructure that makes Roon find itself in this state.
As a workaround, we found that restarting Roon solves the problem for most users. If you encounter this problem, a restart should delete the problem. If this is not the case, we invite you to contact our support team.
