How do I download an icon I purchased on Android to my iPhone/iPad?

Currently it is not possible to re-download on iOS device an icon set that was purchased on Android. Re-purchase is needed.

However we are planning to make it possible to download icons that were purchased on either OS in the future. Please be patient as this takes some additional development and restructuring of purchase mechanisms, but in the future purchasing once would allow you to download the icon on both Android and iOS.
