Changing the date in the analytics view doesn't update the metric numbers in the tag breakdown.

In the analytics view, three metrics are highlighted at the top: delivered, open, clicks. These should be unique opens and unique clicks. The total number of opens is essentially always irrelevant.

In the engagement view for a specific tag, you can't see the number of delivered emails. The absence of this metric makes the tool difficult to use.
In the reporting section, the line chart displays the open rate but not the unique open rate. This is ineffective because some people open the same email multiple times, skewing the statistics.

The documentation for the webhooks is broken, the data we receive are not what is described in the doc.
