Description of Issue

On opening iPad app today was advised not logged in to Qobuz (or words to that effect). Found various support references to potential fixes and tried shutting down core an powering host down. Also tried renaming Roon cache folder to old and starting core & logging in to Qobuz.

None of it worked, please help.
First time on here so apologies if I’m in the wrong place or incorrectly formatted.

Qobuz account fine & works on all other devices.
