Particle Console -> Products -> Events
I can see the events getting in from the devices (sampleCount = 7920).
However the logs of the WebHooks (Azure IoT Hub) with “particle-internal” are missing?
I don’t think the particle internal events have ever appeared in the product event log, because they’re not product events.
If you go into the account of the owner of the device, and view the Events tab there (top level, not in a product), the trigger and particle internal events should appear there.
In the last screenshot, you’re viewing the account’s event log, not the product event log, at least based on the URL in the curl command.
