My phone stopped ringing and I no longer get text alert sounds after the update. After talking to Apple, my phone went from bad to worse. We reset my phone, erased it and now its set back to factory settings because that's the only way it'll work. We tried to do a back up from iCloud only to find any backups I have are now corrupt. So the "engineers" are looking into it and in the meantime, my phone is worthless. It rings. big deal. It's not communicating with my iMac, or my car. My iPad wouldn't connect to wifi. This update ruined the smooth communications between all my devices and its so bad, I'm not sure I'll get back what I had. Not very happy with Apple at this point. The latest updates, 13.1 and 13.1.2 did nothing to help.
