Playcanvas tools not working

Hi -

I’ve got an instant tracking build that previously worked on my phone. That version still publishes fine off the 1.57 engine.
This is that version.

I’ve forked this version and republished a build and the camera feed isn’t showing now. No idea what as they’re both the same.

is this a permissions issue ? I’ve seen this post, but it doesnt explain why one works and one doesn’t as they published off the same playcanvas build.

ok cheers !
