Daggerheart group and content sharing help needed

Hello, I am setting up a daggerheart campaign and am running into some difficulties.

I have linked my roll20 subscription and it says I am at 0/0 content shares. My roll20 subscription is plus, not pro, if that matters. Additionally I have set up a group and the players that I have invited are stuck in the lobby. One has two instances of himself in the lobby and both say “invited”.

Please advise.
