Box Webhook v2 - Webhook created but not working. Missing Address and Trigger

I am seeing this strange behavior starting today.

Up until now I was able to successfully create a webhook using the box sdk function CreateWebhookAsync for c#. This used to work as expected.

Starting today I am not able to have a functioning webhook as the Address and Trigger information seems to disappear.

var webhook = client.WebhooksManager.CreateWebhookAsync(whr).Result;

In the webhook variable above all the values that have been set are visible(Address, Trigger and Target) but the

when I try to see the information using 'client.WebhooksManager.GetWebhooksAsync()' method, the Address and Trigger values are missing. So apparently the webhook does not have a trigger or a URL to function corrrectly.

Any thoughts?

Another behavior I noticed is that webhooks created using a developer token disappear as soon as the Developer token expires. Is that assumption correct?
