There are a number of issues you should consider when using Google Maps background mapping:

1. When your report loads, the map will be adjusted to one of 18 Google Maps zoom levels. This means that your base geography may not fill the map area in the same way as it would if you were not using Google Maps background mapping. To adjust the amount of Google Maps background shown around the Base Geography, you can change the size of the Map component using the Designer.

2. Animated map zooms are not supported for the reason given above.

3. World maps will not work when Antarctica is included. In the Web Mercator projection the north and south poles cannot be projected. For this reason reports published with a world map where Antarctica is included will malfunction when using Google Maps.
