I have a strange behaviour on the ARCamera object (but only on ARKit device compliant, ie: iPhone X for now).
When all trackers are lost, the ARCamera is set to the position (0, 0, 0), even if I set another position in Update() function (I would use the gyro: trackerless mode which is working on all my others devices)..
I need to have the setting "FIRST_TARGET". It works fine for others devices (iPhone 5 and 6 and even under Android).
I hope help or a bug fix !.
Thanks in advance,
