Hi not sure if this is a bug..
If I have a scene in Unity, with a cylinder target & that target is in view of the camera when I press Play in the editor, I get message "Trackable Cylinder Trim Lost" and no AR content. If I move my cylindrical target out of the camera view and back in, it works fine and I see the AR content. If I start the scene with the target hidden and then move the target into view it works fine.
What can I do about this?
