We are aware of an issue which has started to occur from today - 15th August 2018. This issue relates to customers using their own InControl Appliance or Virtual Appliance. These customers see a message across the Google Maps image (which is displayed darker than normal) “For development purposes only”.
This message appears because Google changed their Google Maps API overnight. We are implementing a fix for this issue affecting ICA / ICVA in firmware 2.7.3 that will be available within the next couple of weeks. This new version will allow customers to enter their own Google Maps API.
However, customers can change to OpenMaps which is supported from firmware 2.7.1. You can make this change from Organisation Settings -> Map
