Proximity Analytics not Working

I am having an issue retrieving analytics for my application. Here are the steps I followed:

The application works - I get events on my local test UI as I enter and exit zones, and I see the telemetry is being uploaded in the console.

However, when I hit the API, I get no data at all:

“meta”: {
“total”: “0”
“data”: null }

Is something not setup on my account correctly?

Any Estimote engineering help here? I am trying to complete a POC for a large commercial opportunity.
