We are using Unity 5.3 with Vuforia 5.0.10, and a classic licence. For some reason every now and then a new build will not work with our paid licence!
The dataset is loaded successfully but will never initialize tracking, sometimes swicthing back to a free licence works, not often. As far as I can see via git logs nothing is changing code wise between these builds, only simple transform and material changes.
Any ideas what could be happening here?
