You’re basically asking for fully mobile Roon. There are many requests for that and it’s been acknowledged as on the road map - without date prediction.
That implies mobile access to local tracks on a home computer or Roon server, which, while would be very nice, is not what I’m asking here. As an interim step, I’m asking for full Tidal access via the Roon mobile app.
I think what’s being asked for in fully mobile Roon is not necessarily just access to local tracks. The product could include several strands, and tidal streaming using a mobile connection (as the Tidal app already does) could be included if they want to. And bearing that in mind, I think it’s vanishingly unlikely that they would devote the time to an interim measure of including Tidal but nothing else.
Personally I use the Tidal app on my iPhone when I am travelling. That works ok for now.
