thanks.
this may be down to an account thing. while the qobuz web portal said account active, and roon core said logged in fine… as it turns out my credit card has a new expiry date and it looks like qobuz suspended my account even though it wasn’t noted or communicated in any way. they clearly have a pay portal/db to account comm issue… but… i may have forced it by changing plans and re-inputting payment credentials… so, thanks for the help, much appreciated.
