Google maps appears in blocks
Today I noticed that the Google Maps app on my ipad2 is appearing in blocks as I zoom in or out. Each adjoining block shows a different but unconnected part of a map (bit like a jigsaw puzzle.) I thought it might have been a slow server, but a speed check of my wifi showed speeds in excess of 25Mbps so it wasn't that. If you zoom in closely, the blocks disappear, but it very annoying when you zoom out to see up to 50 square blocks onnthe screen. Any suggestions?
