I installed Public Beta 1 on both my iPhone 6s and my iPad Pro over the weekend. While my iPad Pro completed scanning my photo library for faces overnight, my iPhone seems to be stuck halfway. There is no indication in the People album that the scan is still taking place (such an indication was there for a while, but no longer), but the number of photos attached to each person is far lower than on my iPad. Does anyone know if there's a way to restart the process? Either from where it is now, or from scratch? Or if there's even a way to tell if my phone even KNOWS that it still has a job to do?
