So there's over 400 people, in this thread alone, reporting slowness with Mail, including Exchange accounts! Imagine how many thousands, or tens of thousands, of users are affected? I work in IT for over 30 years, and I know for every customer that takes the time to report an issue, there are multitudes just suffering quietly! Probably because when they have contacted Apple in the past, Apple was in denial... Apple - OPEN your EYES - you have a problem and it's NOT yet fixed even in iOS 11.0.3. Fix it!!!! At least have the professional courtesy to update all of us PAYING customers as to the status. Don't bury your heads in the sand...
Is there a place on Apple's site where they track known bugs, reported bugs and the status of each? Or do we just have to hope Apple has little sticky notes somewhere tracking all this insanity?
