Just tested it and Image tracking is working for me in 5.2 (model scaling was a bit off but think that’s just because I was using a larger image on the screen, not a print on paper. Tracking and orientation was all fine though)
I think it was working in 5.3 last time I tested but AR tracking is completely unusable for me in 5.3: UE5.3 AR Actor Location Not Positioning Correctly (IOS)
