Apple One Plan Not Showing Music Suscription

I have an individual Apple Music subscription but have recently joined an Apple One family plan. On my phone I can't see Apple Music or iCloud as a 'shared subscription' but the organiser does see that this is shared with me. Another member of the One plan also has no issues sharing Apple Music. I have tried signing and back into iCloud and have not been able to resolve this. Any help is much appreciated!
