Labels not displayed for a cluster of points in ArcGIS Online Map Viewer

Description

When attempting to display the labels from a cluster of point features in ArcGIS Online Map Viewer, only one is displayed.

The map below demonstrates the issue, where the labels for Point A, Point G, and Point J are visible but the labels of the other point features in the cluster are not displayed.

Cause

The point features are too close to each other or are overlapping. Therefore, some labels are not displayed at certain zoom levels, preventing all labels from being displayed at once.
