When I load the “Activity by key” page I see some of our keys and the number of requests they made. When I filter the results with the API Version dropdown and hit search again, it lists a bunch of keys but all of them with 0 requests. The Last Access column shows 2015 years ago. It doesn’t matter which API I select - the same thing happens. When I select “All” it shows the correct results again.
We’re aware of the issue - thanks for raising it.
