The latest versions of iOS (11.0.3) and iTunes (12.7) seem to have many bugs. Most importantly, this software combo WILL NOT CURRENTLY SYNC RINGTONES with a great deal of success. If you want to sync ringtones to your iOS 11.0.3 phone, please do not update to iOS 11 or iTunes 12.6+. If you have, please try some of our recommended third party software listed below (on the sidebar) which I can confirm is still working. -Brendan
