What does “Not Set Up” mean on the Subscriptions screen?

On the Subscriptions screen, a subscription that isn’t currently applied to any group is shown under Not Set Up (or Left Groups if it belongs to a group you’ve left), and the action is called Move.

Tap Move next to that subscription, then select a group. Once moved, that group will be covered by the subscription (and the group should stop showing paywalls like “Group needs a plan,” if that was the issue).

If you don’t see the group you want to move it to, make sure you’re a member of that group on the same account and that it doesn’t already have an active subscription, then try again.
