    (Also, was testing on a Pixel 2 - according to this link here, that may be relevant for my case of video freezing - unsure on the tracking lag part).

    Still and issue for me in 2019.1 also. Preview package 2.1.

    Using an image target (2D) to trigger a video. Video does not track well (jumps around) and video hangs after 3-5 seconds (varies a bit from attempt to attempt).
