Hello, I am looking for some tips. Here is my set up:

1. Child A has a google voice device in their room
2. Child B has a google voice device in their room
3. Child A & B are both in my Google family group
4. Parent A (Me) setup a spotify account, assigning Child A & B each a spotify account within the family plan
5. I linked Child A & Child B to their respective spotify accounts in Google Family
6. When either Child A or Child B say 'Who am i" to their google speaker, the speaker responds correctly.

The problem:

1. When Child A plays music from google assistant, it plays from Parent A (me) spotify account. When Child B plays music from google assistant, it plays from Parent A spotify account. When Parent A plays music from his phone, it plays from Parent A spotify account.

Spotify only allows one listener at a time, so we are forever kicking each other out.

The question:
1. Does anyone have a solution for the above? Google assistant is the only way my children listen to music. They don't have phones or other smart devices.

2. If there is no solution, is there some other music service that might work better? From my point of view, the various streaming music services are all the same, so I'm happy to jump ship if that will allow us to listen to music.

Thanks!
