Google has stopped providing service for Skyleader's embedded Google Maps and caused the blank map view.

"Dear Skyleader users,

Due to Google Maps just changed its service terms without notice in advance, Google has stopped providing service for Skyleader's embedded Google Maps and caused the blank map view. Our software team has been mobilized to fix this problem and Skyleader's embedded map view will soon recover with a brand new look. Before we release the new map view, you may still use the full-screen map button to observe the tracks of your loved pigeons in Google Maps. Your patience is very much appreciated. Map function is the kernel of Skyleader, and we will be coming back with a more fluent embedded map soon."
