I have a problem with a game on my iPhone that might possibly be fixed by resetting the iPhone’s IDFA. I understand that there is a way to do this. Could someone tell, or show, me please?
In case I don’t get asked for the information hereafter, I have an iPhone 16 Max Pro running iOS 26.2.
iPhone XS Max, iOS 18
Apple's IDFA (Identifier for Advertisers) was a unique identifier for mobile devices.
This feature was deprecated/retired some years ago. If memory serves correctly, this functionality fully removed during the iOS 14/15 lifecycle.
See: How do I reset the advertising identifier… - Apple Community
Also note that this ID might be only one of many ways that advertisers attempt to track you.
