I have a TIDAL Premium subscription already. Do I get a 30 days free trial of Plex Pass if I upgrade to HiFi?
If you choose a new TIDAL HiFi subscription, you will get 30 days free of HiFi and Plex Pass; however, it will not be connected to your TIDAL Premium subscription.

Is there a family plan with the TIDAL pass?
