Yes. I found 61 out of approx. 700 of my UK TIDAL favourites have silently had their playback rights removed. It was painfully slow going through them all in TIDAL’s app to find them (no hover-over play button) and replace them.
Intriguingly and annoyingly, I was able to replace the vast majority of removed albums with like-for-like equivalents, which suggests that TIDAL has been doing some housekeeping which involves deprecating certain IDs and replacing them with new ones.
