Inside the Photos app there is a people album that is supposed to be automatically updated when a device is on charge. In iOS 10 this worked for me, as in it updated. Yes, there were issues, but it updated. So here's my issue I upgraded to an iPhone X about 2 months ago. Since upgrading Photos has never completed the face detection, even though I charge it multiple times a week. Also I am having issues with my iPad running 11.3 updating, but I am under the impression that this might be a beta issue. Prior to my upgrade I had an iPhone 6S running iOS 11, but I am not sure if it was up to date or not. Here are my questions: Is there any difference for the processing with a charger, as in wired vs wireless? Is face detection completing for you? Do you have any suggestions to try? I have rebooted.. How does the iOS 11 face detection syncing work? I don't understand why my Mac can't scan the faces and just sync to other devices? Thank you for your help!
