Big oversight in my op description…. I’m wired to my router by Ethernet so it’s not a WiFi issue. The interface is a convoluted mess. I’ve got my iPad connected to the ZS using the Ifi.local network connection for setup, which seems solid. Then I’m using the iPad Tidal app, which seems pretty solid, to select music. The tricky part, where the problem seems to reside, is in the Tidal Connect app process where you start playing music on your iPad, then select an alternative destination. This music output icon brings up all the connected network devices… in this case including the ZS. Just doesn’t reliably connect or stay connected when you navigate to new music…
I’ve already accepted the likelihood that I’ll have to eat this purchase, since I’d be reluctant to sell it on. I do have to say that Ifi support has responded to tickets within a day… sometimes with useful suggestions. But I suspect the Tidal Connect to ZS interface is just ill-conceived and not ready for consumer use.
Any suggestions are much appreciated. Stunningly bad interface for a product with so much potential.
