How should SharedSpatialAnchor example work?

Now, I'm trying shared spatial anchor but I can't get how example should work.

I created 2 account and signed in with each account on different devices.

I build example and deploy to each devices. 

Then, I run example on each devices and create room on one device and join that room from another device.

I spawned one cube on first device and create anchor and make it shared status and aligned status.

On another device, I can see spawned cube but position and orientation isn't same against physical space.

Do I have to do anything other to make it same?
