Question Faulty trackableId of ARPlanes in Unity MARS

Hi,
I am using the ARFoundation ARRaycastManager and ARPlaneManager to get the id of a hit ARPlane. This works fine in the .apk but not in Mars. In MARS. I get the plane id 0000000000000000-0000000000000000, which is not an available plane id. The correspongin Plane is called ARPlane FFFFFFFFFFFFFFFF-0000000000000005 in the Hierarchy.

Code (CSharp):

1. s_Hits[0].trackableId

However getting the hit position still works fine in MARS and returns the correct position.

Code (CSharp):

1. s_Hits[0].pose.position

I tested this in Unity 2020.3.3f1 + MARS 1.3 and in Unity 2019.4.3f1 + MARS 1.2

Is this something that MARS is currently not able to do, or is some additional setup required?
Thank You.

 

Hello
im working with DoAugMenRo on the projekt.

yes, it works fine if we build the apk and test it on a smartphone

but in the simulation Environment the plane what we want selected is null. What DoAugMenRo had forget to say is
every plane give us in the simulation environment the same trackableID i think there is something wrong.
