I feel like i must be missing something obvious, but we have an app that we have a webhook subscription set up for, and we have received many, many events from that webhook over the life of this sandbox app.

The subscription we have set up is for SMS webhooks, but no matter how many we've received, it never seems to "register" on RingCentral's side. The part that we're confused on is the "exercise all requested permissions" for the "webhook subscriptions". It doesn't seem to reflect that we're received any, but we definitely are. Every time we respond using a phone to a text that's sent via ringcentral, we get a post from the webhook letting us know, which is exactly what we were after by setting up the subscription.

Is there some trick to this that we're missing? are we reading this wrong? or some other requirement that needs to be met in order to get this to show that we are indeed using the webhook subscription? Or have we somehow requested the wrong permission? Any help would be so greatly appreciated!
