I am having an issue with an app that I can replicate in a CodePen. The issue occurs when using Google Maps on two different page states. When navigating from one map to another map, the second map does not load. If you navigate from a map, to a non-map page, and then to the other map, the map does load.
Home -> Map 1 -> Map 2 // Does not load map on Map 2
Home-> Map 1 -> Home -> Map 2 // Does load map on Map 2
See the Pen Ionic Google Map on Different Tabs by Joe McFrederick on CodePen.
