Why is Max Value not showing any value in the summary metric?

Question

Only Average Value is displayed, I cannot get it working with Max Value

Is this by design or am I doing something wrong?
(I tried sending the metric with unit count, value, or an arbitrary string, same result in each case)

Answer 1

Currently there is a bug that is preventing this from working correctly. The New Relic team is aware and working on this issue.
