I have about 1,800 tracks starred in Tidal, but only 30 of them show up in Roon.
Initially when I noticed this, the 31st track was shown as “unavailable.” The list Roon displays is apparently unsortable, but I sorted my Tidal track list by title, and it looked to be the same. I un-starred the 31st track in Tidal, and refreshed Tidal in Roon. Still only 30 tracks show up, sorted slightly differently, and no 31st “unavailable” track appears.
Update: #31 “Unavailable” is showing up again. Also, resorting the Tidal list (after un-starring the former 31st track) shows a different sort. (Titles with apostrophes and other punctuation sort first now in Tidal and Roon).
In other news, when #31 “Unavailable” shows up, tracks cannot be played from the list. Play buttons don’t respond.
