It would seem if you want to ‘heart’ it in Tidal you’d want to ‘heart’ it while doing so in Roon. Thus, add the album/track to Roon and make it a favorite in one user action.
But we can’t. It’s stupid.
That’s a good point @Rugby. I hadn’t thought about it from the perspective that a ‘like’ in Tidal is the only means to add to the Roon library. I can see that it becomes more complicated.
I won’t give up hope that Roon can come up with a solution, but I stand corrected that the situation now is ‘stupid’. It’s inconvenient.
