No custom ringtones on iPhone 8 Plus/iOS 11
After receiving the iPhone 8 Plus today, backing up my iPhone 6S Plus (running iOS 11), there are no custom ringtones.
This link does absolutely nothing to resolve the issue. It seems to have been written for earlier than 12.7 iTunes.
Use tones on your iPhone, iPad, or iPod touch - Apple Support
If I try to drag anything on my PC from the window with the ringtones open to iTunes, I get a circle with a line through it as I try to drop it (meaning you cannot do this). If I go to File - Add File To Library in iTunes, it places the files that are M4R format into the regular music song list. You cannot drag them from there to the Tones or any other spot in iTunes.
hmmmmm.... seems Apple might have a hiccup here.
