A couple of days ago I updated to Unity 2018.2.5f1 (as the iOS app I had been working on stopped working on my iOS device). I also updated to Xcode version 9.4.1 (9F2000) so that it would support the iOS version on my iPad - iOS 11.4.1 (15G77).
As a result the AR app works (the camera seems to be sensing) but the live video background is not being displayed, and just shows black.
Does anyone have a fix for this issue? Thanks
