Which verson of andriod are you on? Im on 6.0.1 and they moved the Google category in Settings during a recent update.

Generally, it's the same. Go to Settings > Google > Ads > Reset advertising ID.

Do note that if you have made an IAP, you will not get the 20 gold ads. This resetting ID is to ensure you get unlimited ads for things like speeding up upgrades, car delivery time or service time. Overall, if you have watched about 10 in a row, the ad inventory is used up, resettting AD ID allows you to have a new batch.
