Ditto! And the "genius" at the bar first told my wife to reset all settings (didn't work), and then to reset and restore her iPhone from our backup, which then required her to do the same on her Apple watch, and it still didn't work. On top of that, the ringtones were no longer on her phone, couldn't be downloaded as Ritchiescritch suggested or by syncing with iTunes, and could only be restored from our Time Machne backup on our Time Capsule - complete waste of 3 hours!
The "genius" at the bar also went to the back of the store to check his problem DB to see if others had seen this issue - he claimed not. That is patently not the case as google searches and this forum clearly demonstrate! He suggested I submit the issue to apple.com/feedback which I did but doubt that will result in any action.
The lack of regression testing of OS11 on basic features for which customers have paid to utilize is extremely disappointing. If there is an Apple support resource monitoring this forum, I'd be very interested in your perspective on the issue, the lack of transparency, and how Apple intends to resolve it and educate your "geniuses" to deliver more analytical value than "erase everything and start over" - this is NOT the user experience that Steve would find satisfactory.
