Oculus DK2 works with 1 tick in 5.3.3 - not in 5.4.4, or 5.5.1

So I am testing an Oculus Dev Kit 2 and if I create a new project in 5.3.3 and tick the vr box then when I run it vr works straight away in the editor.
This does not work in 5.4.4 or 5.5.1
So did something change/break? Was DK2 support dropped?
