They say it's a hidden button in the upper left of the screen that shows several other G5 games when you are opening the game. When you hit the button it will automatically go to the page you need and it automatically sends that IDFA number to G5 but you can write it down and send to them. I found the button on my device but it dosn't work on my husband's device.
