Xperia 5 mkII - 'Swipe Up On Home Button' missing

[Deezla]

I've just moved from an Xperia 5 to the new Xperia 5 mkII. The home button navigation setting for 'Swipe Up On Home Button' (also referred to as ' Pill home button' or '2 button navigation' is missing. 

As a very happy Xperia 5 user this feature/navigation method would be a deal breaker if it's no longer a feature in the mkII. I've tried the only other 2 options left for a few days trying to get used to it but I'm finding it has totally made the phone a pain to use. Why would this feature disappear from a mkI to a mkII? 

Any help would be really appreciated bit I fear it's simply just gone. I've only had the phone a week so if it can't be resolved I will be returning the phone under the 14 day cooling off period. Sounds like a small thing but it's really ruined my love for the amazing Xperia phones

What a shame.

Try this:

Open settings and type gestures.

It'll bring you to a page where you can select System navigation.

There you'll find this:

 O and btw, you should really try to get used to gesture navigation.

The slide from the side to get back to where you were is a great option.
