It would be very beneficial to add eMail alerts that will work with. thresholds and alert when those are reached or any significant anomaly is being detected.

When a customer is losing 20%+ of its website traffic and doesn't constantly look at the executive summary, especially in the weekly mode, they won't necessary see the anomaly. When switching to custom date range, website traffic will not be shown.

In this case, the customer did not see they have lost 25% of traffic overnight.

This is where an immediate alert eMail notification would be needed.
