My phone got stolen today, I managed to lock it within a few minutes from my Mac. I double checked to see if it would still be traceable after erasing it just in case. I did so after I came across this note in Apple Support - https://support.apple.com/en-gb/guide/icloud/mmfc0ef36f/icloud
If you erase a device that has iOS 15, iPadOS 15 or later installed, you can use Find Devices to locate or play a sound on the device. Otherwise, you will not be able to locate or play a sound on it. You may still be able to locate your Mac or Apple Watch if it is near a previously used Wi-Fi network.
Since erasing, the location hasn't updated and the option to play sound has gone so I feel this is either wrong, or the thief managed to turn the phone off. Has anyone else had the same issue?
