@nonsequitur said in Tidal music catalog is not displayed. "Album .........not found (404) (2001)":
Finally, I have managed to update the collection thanks to the advice of "nonsequitur" to delete the albums that Tidal has been disabling from my mobile app and thus I could finally make all the music appear again in Strawberry.
Many thanks to the advisors and collaborators who have helped me find the solution!
