I have the same problem. Connection to Qobuz lost after System Update. Cannot connect again. Connect Button turns from blue to grey, but nothing else happens.
After I open Rose 250a and my app on ihone, I must login on Tidal to my Iphone.
This happens everytime I open rose app on my ihone. Before update, never happend this.
I lost QOBUZ after the last UPDATE.
I write my email and my password but very is no effect. It doesn't works.
Someone has got an idea ?
