My current plan is “Virtuoso”. I couldn’t play Tidal on my raspberry pi anymore. As a test I have deactivated and reactivated my device “Activate my volumio on devices …” in my profile. No result. Now I deleted the Raspberry pi under devices and wanted to add it again. Unfortunately I can’t add any device.
I have a similar problem. I am currently on two weeks trial, I installed Volumio on my RPi4 and it worked just fine. I installed Volumio on a new SD card and put it in the same Rpi4 and Tidal Connect does not activate. I am logged in and my current plan shows Virtuoso. If I want to activate Tidal Connect it says " Feature not available with current plan". If I insert the old SD card Tidal Connect is working, Qobuz integration as well.
Now I tried by deleting the RPi from Volumio devices, did a factory reset to Volumio and now my RPi does not appear under “Activate MyVolumio On Devices”.
