This is a heads up to anyone relying on Roku billing push notifications. We use these to track which users have cancelled and which recurring subscriptions have renewed, such that we can appropriately provide content to them. Apparently on July 19 (while I was out on extended leave), Roku added a checkbox to the website on this page:
https://developer.roku.com/api/settings titled "Stop sending billing notifications". The default is set to checked, so we stopped receiving them. Until I figured this out today.
It seems to me that if a developer had put a URL in that box, Roku should have been able to guess that we wanted to keep the notifications coming.
The result of this is that we will now need to make a large number of requests against our user base through the Roku API to verify that accounts were not modified during this period.
PS. I had to generate a new account because I was not able to log in to the forum with my old account. Even after password resets, etc.
