I've activated ScreenTime but it will randomly rest/erase all statistics a fews times a week or not record entirely on some days. I'm running ios 12.0.1 and have been having this issue since installing the public final version of iOS 12. I did not install any betas on this device ever and I don't have ScreenTime syncing between my other iOS devices. Is anyone else having this problem? To attempt to fix this problem I've tried turning ScreenTime off and then on again and restarting my phone–but nothing works. Also, I have previously had the default device name of my iPhone set to "My iPhone X" (I did this shortly after installing the public release of iOS 12). However, last week I changed my iPhone's device name simply back to the default "iPhone". Yet the ScreenTime screen still is "My iPhone X" as the device name. It's really weird. Any help?
