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?

I can fix this by installing the latest oculus setup tool but then it is much harder to develop with the dk2 because the runtime complains about dk2 not being setup properly (ignore) and you have health warnings and the lobby showing up (this makes it bad for use as a sales or exhibition device but no doubt an oculus issue)
