Hey all, I could use some help. I updated to iOS12 on my 6s Plus. "Hey Siri" has stopped working. I've done everything I can think of, including: 1. Turned Siri on/off and retrained it many times. 2. Turned on/off dictation. 3. Hard-restarted the phone numerous times. 4. Various combinations of the above. It worked just fine before the update. I can use Siri by typing into it (triggering Siri with the home button). My Internet connection is working fine. It's like the phone is deaf but only w/r/t Siri. I am able to make it work one time, after turning Siri on/off and retraining then immediately testing with "Hey Siri." But as soon as I exit that settings routine, Siri doesn't work anymore. It's very frustrating and I cannot find anything on the 'net talking about this problem upon updating to iOS 12. Any suggestions? Thanks very much in advance.
