Music on MacBook won't login to family plan

We recently expanded to a family plan to our Apple Music subscription. Logging in as the new user on iOS works fine, but on MacBook Pro, I enter credentials, dialogue box goes away like it accepts it, but nothing changes, nor do I get access to the subscription. In settings, family sharing is on for both accounts, and the 'home' account even says the new one is connected and sharing in the family sharing for music... Extremely frustrating! Please help!.
