I’ve had a similar issue, even after updating to V2 Innuos Sense. 3 weeks later, 3 emails to support an no answer. I suspect they have been overwhelmed with this release.
Since the upgrade I found the OS thought I didn’t have an internet connection, but after numerous reboots it now see the Internet. But still no album art.
I also can’t use Roon with Squeezlight, it would be nice to compare Squeezlight with Spence and pick the the best sound quality. With no album art and no comparison I’m back to Roon and hoping I can roll back to 1.4.9 and let them stabilize this release.
Do understand that some have working upgrades, though this is disappointing to me that after 3 weeks not a single reply. If you upgrade do know there is some risk.
