This is my first attempt at creating a Web Clip to launch a FMGo 13 (fmp12) file.
I used the new Apple Configurator App on a Mac to create the web clip and installed it on my iPhone 6 running iOS 8 by emailing it to myself.
The web clip has a URL for a file that is on the device (not hosted).
The URL is
(FIleName: IPhone Training assistant.fmp12).
The Web Clip launches FM Go but goes to the recent files screen rather than launching the specified file.
