TIDAL subscription is active but Music dashboard still showing TIDAL ads

Having exactly the same issue. Plex pass member as of last week. I signed up for tidal (separately via a £2 for 90 days offer they had)last night, linked my account via “other services” in settings. Got the confirmation email. Neither Plexamp, nor Plex in IOS let me view Tidal music. I’ve occasionally been able to add tidal music via the web app but it seems hit and miss. My PMS is on a synology NAS via docker if that makes a difference. Anyway to escalate this? It’s marring what has so far been a good experience moving from Roon.
