Azure spatial anchor Unity3d - unable to locate anchor after 2 or 3 hours

Unity3d - Azure spatial anchor - I m using unity’s azure spatial anchor sample project for sharing anchors. I have placed anchor on some location and saved to cloud. but after some hours I m unable to locate the anchor.

Is it after a few hours that you cannot locate it? Or are you not able to locate it at all?

And could you provide some more information?
