I am developing an AR app for iOS in Unity 2017.3.0p2 with Vuforia 7.0.43 and it seems to take an awfully long time (30-60 seconds) for ground plane detection to occur on both an iPad Pro 10.5 and a 2017 iPad. Strangely my iPhone 5 seems to find the plane almost instantaneously. Any thoughts on what might be causing this? More importantly, how can I fix it? Or is it perhaps a bug/limitation of 7.0.43?
Any help would be greatly appreciated, thanks in advance.
