I currently have a TIDAL HiFi subscription which gives me a Plex Pass. If I downgrade to the TIDAL Premium account will I still have the Plex Pass?
AFAIK you won’t get a full Plex pass with the smaller tariff.
Only a few music-related features will be unlocked, like sweet fades and loudness levelling.
Access to Plexamp is also only included in the bigger tariff.
AFAIK the tariffs have been renamed by TIDAL.
