It lists every subscription on the plan in two tabs: Automatic Renewal (auto-renew on) and Manual Renewal (auto-renew off). Columns: ID (links to the subscription), Subscription (days × meals; shown in red with the last error as tooltip when the subscription is on error), User, Last Charge, Start, End, Renew (auto-renew tab only) and Amount.

The Renew cell colour tells you the state: plain = not yet due, yellow = today is inside the buffer window so a charge is being attempted, red = the renewal date has passed, and the text "Impossible to renew! No Price found." means the plan no longer has a matching price row for that subscription.
