Hello mdkeller,
Being able to locate an AirTag that is detected near you (your daughter) is extremely important From the description, it sounds as though she's following those steps without success in locating the AirTag.
- "Tap the alert.
- Tap Continue and then tap Play Sound.
- Listen for the sound. You can play it again if you need more time to find the item."
While your daughter is walking through the right steps, she may find the following details helpful in addressing this prompt further and not being able to locate the AirTag.
If the option to play a sound isn't available, the item might not be with you anymore. Or if it was with you overnight, its identifier might have changed. Find My uses the identifier to determine that it's the same item moving with you. If the item is within range of its owner, you also won't be able to play a sound.
If the option to play a sound isn't available, or if you're unable to hear the sound and you believe the item is still with you, look through your belongings to try to find it. Check on your person, or in anything in your possession that could contain this device. It could be in an item that you don’t check often, like a jacket pocket, the outer compartment of a bag, or your vehicle. If you can't find the device and if you feel your safety is at risk, go to a safe public location and contact law enforcement.
