Bang! and Siri was gone

Hi all,

I may have just found a major bug. Using iPhone 6s and iOS 11 I downloaded the new US Siri Female voice and had been using it with no issues. I updated to iOS 11.0.1 and Siri defaulted back to UK English male. I thought maybe that the female voice had uninstalled. So, I went back into the settings and found the voice. There was however, no download size which to me implied it was still on my device. So I tapped the example to see what she would say. and what happened was I was chucked out of settings completely. no example voice. I went back in and tried again just to be sure I hadn't done something wrong. Again I was just chucked out of settings. You have to completely navigate back when going back in settings. So I made a final flaw I went back in, and this time tapped on the voice not the example and that was it. VO crashed. It was almost like it had selected the voice but there was no voice. I did a hard restart and still nothing. I had come to the conclusion that I was either going to have to try a restore from a back up using itunes or getting sighted help to see if they could log me in and change the voice. When about 5 mins later VO came back on as the default UK voice. I was then able to go back into settings and choose the voice I wanted to use. Not sure if anyone else has seen this but potentially you may lose VO if your not careful. HTH
