Has 3D touch to switch apps been removed in iOS11? One of the best uses of 3D touch in my opinion was being able to push on the side of the phone and swipe between apps in a single, fluid movement. However once I updated to iOS11 I noticed that I cannot do it anymore.

I have an iPhone 6s, this is also the case for a friend of mine who has the iPhone 7.

Is there any option to re-enable it?
This feature was removed in the first iOS 11 beta and the feature did not ship with the official iOS 11 release. 

Apple has publicly explained a technical limitation caused the tradeoff and that a 11.x release will return this feature. No date is given for 3D touch's return.
