  2. In Different session locate the anchor A

  4. Anchor A and B should be now connected

hi @shyam-barange could you describe how the pose is wrong? IE, is it off by centimeters/close? Is it consistently in the same wrong place, or does the wrong pose place the anchor in different places, perhaps depending on where the application was started?

I'm experiencing something similar. My use-case is exiting the session, reconnecting and relocating the anchor by ID and having it be in a location either slightly off with a new rotation, or sometimes supposedly locating the anchor completely behind me and no where near the original location.

I'm having this exact same issue. Unity version is 2021.3.12f, ASA 2.13.0, and I'm building to the Hololens 2.

I'm just using the sample scene for Unity.

The anchor isn't stable both when I turn of program off and on again on the same HMD, and between two different HMDs during a shared session.
