Paid_until continues to be updated even though the subscription has not been paid.
Why is this?

subscription id: "8c4b62f8-bec2-4213-ba7f-3dca6136d6a8",

invoice_ids: [
        "jH5zE8JJXc8u9qqudI14sQ",
        "inv:0-ChDUCJyeG5QDgZCsF642749EEN4C",
        "inv:0-ChCuYcg94qHhcwWoxA9zbcbaEN4C"
      ],

Unfortunately this is a known thing. Basically this was badly named and we plan to rename it in a future version. This field really represents the currently billing end date, but does not actually mean the customer has paid for the subscription.
