URL for App Store Server Notifications changes did not updated

Hi

We have implemented developed in app subscription purchase in this month and enabled server 2 server notifications. However while we are developing this, we use a stage address for it and after we updated the URL after our application goes online with latest version which is including this development.

But we have a problem in this stage because the server notifications still coming to stage URL even if we updated the URL from the app settings (under appstore connect) at least 10 times.

What can we do in order to get those notifications to production URL?
Same problem here.
I updated URL settings on appstore connect still receiving notifications to old URL.

The question here should be how long does it take to propagate changes when updating notifications URL. Second day and changes still not propagated. Looking for answer too...
Any one got info that how long it will take?

In my project, now a part of notifications send to new URL and another part still sending to old URL.
We changed the settings 3 days ago, would like to understand when we can shut down old URL.
Just for people who will check this question in the furture.
After a complete week(7 days), all new notifiactions are starting send to our new URL.
