After upgrading to iOS8, my iPad Air's Siri stopped working and my email stopped loading. Facebook would load only text, no visuals. iCloud refused to accept my password. After chatting at length with Apple Help, who seemed as flummoxed as I was, I was eventually able to do some resetting and changing my password via my laptop. This fixed the problems for exactly one day. Now I'm back to square one with my NEW password being unaccepted, and Siri and email once again dysfunctional. Chatting any more with Apple Help seems problematic: even though they gave me a link to re-open my case, clicking on it only brought up a dialog box that said I was no longer eligible for their assistance (all of about 20 minutes after we had chatted previously). My frustration at this point is beyond description. Is there a permanent solution for all this, or will I have to re-do everything every time I turn on my tablet? Please tell me I'm not the only one faced with this particular dilemma.
