Billing Attempt Never Ready

Hi, for one merchant we are working with, when we tried to create a billing attempt, the ready flag would never turn true, and we could not create orders for this merchant. Any suggestions why this would happen?

Example:

					  {
					         "node": {
							"id": "gid:\/\/shopify\/SubscriptionBillingAttempt\/9746710766",
							"createdAt": "2023-03-26T22:13:33Z",
							"completedAt": null,
							"ready": false,
							"errorCode": null,
							"errorMessage": null,
							"order": null
						}
                                            }

The issue is this billing is pending 3DS verification. The verification link can be queried at the next_action_url of the billing attempt object.
