The region map does not load fully in the initial view. Initially, the region map dashboard is shown grey without loading any data in it as shown in the image below:
Once page is reloaded or refresh button is clicked or zoom in/zoom out is clicked or the map is moved( any action on the page), it loads the data.
In this case, Kibana is a display on Iframe.
The issue is that the Kibana is not able to load region map in the first attempt.
Please let know your inputs on this and when this will be fixed.
