Help! Having trouble sharing scores

I upgraded to a pro account. I've created a group and invited members to join the group. I've created scores and added them to the group.

But... the members of the group can only see the scores I've shared in the Songbook app if they "search" for me, then favorite the score on the website.

If I add a new score, they have to repeat the whole process. Am I missing something? Isn't there a way to have a shared group where the members of the group AUTOMATICALLY will see/have access to the scores that I add to the group?

Thanks,

Steve
