Features you were using before which are gone in iOS 11

Scheduled fetch and notifications have been disabled for favorited folders in native mail App for non-Push IMAP mail accounts in iOS 11.
Now in iOS 11 the Scheduled fetch and notifications for favorited folders happen only for the Push supported mail accounts.
These fetch and notifications used to happen without any problem in iOS 10.3.3

One click unsubscribe banner no longer appears in native Mail app for spam or messages from mailing list.

Still shows up for me.

I miss the curser control buttons that were on the iPhone 6 Plus keyboard in landscape. Why couldn’t they do as the next keyboard and let you move the curser by dragging over the space key?

Oh yes and one other feature I liked before iOS11, I had a battery!!!!
