No Metrics (Battery, Memory, etc) stored in Organizer

Hey Everyone, I'm trying to understand the thresholds required before the Metric section of Organizer starts populating?

We have one app with several thousand workouts logged on it everyday, and have never seen any of these populate. We get crash reports without issue, but nothing in Metrics.

Clicking "Learn More" I can confirm:

• 'Step 1' is done, and we are supported (WatchOS 7, and iOS 14).

• We are distributed on the App Store

• Users agree to share data. As far as I can tell there is nothing we need to do here, it's part of the iPhone onboarding that asks if you are cool with sharing data. We see other analytics data for people who opt-in, so I'm assuming they opt-in for these metrics too.

• We are signed in, confirmed by being able to download Crash Reports.

Finally I see this line:
"To provide accurate results, Metrics organizer reports require significant usage of your app, and each metric has different usage thresholds."

If you don't mind sharing, could you help give me an idea as to whether or not I should expect to see data here?
Thanks in advance.
