With most mobile devices, when you tap on the download now link a pop up asks you to confirm the download. In some older devices this may not happen.
In most devices the download progress is displayed by a blue line moving across the top part of the screen, a blue circle moving clockwise in the upper right hand corner of the screen, a blue circle with a downward pointing arrow in the upper right hand corner of the screen, or a display at the bottom of the screen which shows the file size "counting up". If you see the blue circle, tap on it to display the progress.
When movement of any of the above noted activities stops, the file has been downloaded from our store to your device.
