I access Tidal through Roon on an iPad Pro. Because I fear all the Tidal picks might go away someday, I take screen shots of my Roon screen (record covers) every time I fill the screen up with new selections. That way if anything happens to Tidal or my Roon database (which I do back up) I have a record of what my selections were. I too am somewhat paranoid about the future of Tidal, because it has allowed me to hear so much new music!
