Apple Music Profile on child account

Hi,

Sorry if this is posted elsewhere but I’m having real difficulties with trying to resolve this. So this is the situation:

We have a family setup, My wife is the organiser and I’m a parent and we have two child accounts as part of the family. I have an Apple One subscription shared with the family. Everyone seems to be able to use Fitness +, Apple TV+, Music, etc. However, my daughters do not appear to be able to create Apple Music profiles (the setting under the screen time content restriction is turned on to allow profiles). It also says they have no subscription at the moment. Finally it appears to have the added issue now that when in the car and car SharePlay is tried it says the function is not allowed for my daughters, I assume due to not having a profile.

Anyone got any ideas what the issue may be or how to resolve it?

Thank you
