I've set up a URL on my server to receive auto-renewable IAP status change notifications per this article:
https://help.apple.com/itunes-connect/developer/#/dev0067a330b
And of course I've provided my URL to iTunes Connect via my app's main settings page.
However, I'm receiving neither update notifications nor any kind of message indicating that there's a problem.
Help troubleshooting? I don't even know where to start.
Thanks!
