Tidal albums get lost

Track replacement suggestion for songs becoming unavailable on streaming services (Qobuz/Tidal)

It is common for individual songs to become unavailable on streaming services. This means that these tracks are no longer available in the playlists that have been created. However, very often it is only a change of the album or version of the same album and for this reason you have to manually find the track again and replace it with the existing track in the playlist. It would be a good improvement of Roon if the replacement title would be suggested automatically.
