Subscription Update Flows Triggered In Incorrect Order

[Santhosh-Hanabi]

• I am calling updateSubscription and updateSubscriptionItem method when the user upgrading subscription
• Sometimes it is correctly triggered in correct order and proration charges calculated correctly
• Sometimes Order will be incorrect
• Assume i have Product A with Variant A and Variant B. I need to update my plan from variant A to variant B with some additional quantity. i passed variant B id and quantity and calling the methods in correct order.
  i will add my code below

  const updateSubscriptionPayload: UpdateSubscription = {
          invoiceImmediately: true,
          variantId: parseInt(variantId),
        };
  const { error } = await updateSubscription(
          subscriptionId,
          updateSubscriptionPayload,
        );
 const { error } = await updateSubscriptionItem(subscriptionItemId, {
          invoiceImmediately: true,
          quantity: quantity,
        });

  ,

• But it updates variant A with quantity and later changed to variant B with one quantity
