MOTO G无法定位手机

arbing

新入手MOTO G，在motorola网站用lost device功能找手机时，总是无法定位，出现提示：Not SupportedThis feature is not supported for your device.
可能是什么原因啊，该怎么解决，请各位帮忙。

PS：已经按照提示设置：

If you have already cleared this notification follow the steps below:

• Touch [size=1em]Settings
• Touch [size=1em]Security
• Set a Screen Lock if you don't already have one
• While still in Security, scroll down and select [size=1em]Device Administrators and activate [size=1em]Motorola Device Policy
• Remain in Settings on your device, select Motorola Device ID and choose or add the same Google Account you are signed into here.
• Also in Settings, select Location Access, and turn the Access my location switch to ON. Ensure GPS Satellites and Wi-Fi & mobile network location are selected.
• You will now see your device in My Stuff.
