Have upgraded to iOS 10, 10.0.1 which is apparently the one the same version that is going to be released to the general public next week.I have however run into one annoying issue with the normal email app. In iOS 9, you could bulk delete all mail in the inbox of an email account. However in iOS 10, this option has gone, and you need to manually select each email, before the 'bin' button is activated. There is no option to 'select all'. I am wondering if this is a bug or they have removed it, or am I missing something? I did compare it to an ios9 device and the feature is in ios9, but gone in ios 10.
