Murcielago You explicitly asked about resetting ad ID, but if you're interested, you could also delete it entirely in the same menu mentioned by wizoatk : On devices that have this feature enabled, you can open the Settings app and navigate to Privacy > Ads. Tap “Delete advertising ID,” then tap it again on the next page to confirm. This will prevent any app on your phone from accessing it in the future. source: https://www.eff.org/deeplinks/2022/05/how-disable-ad-id-tracking-ios-and-android-and-why-you-should-do-it-now
