Unity 2017.4.40 and Integration v17 on Quest not working

Hi,

I'm trying to upgrade from Unity 2017.4.27 and Oculus Integration 1.35 to Unity 2017.4.40 and Integration v17 (1.49) but have issues when deploying to the Quest.
It seems the SDK won't initialize (SDK 0.0.0. is printed in the log). I've had this issue in the past on PC but never on Android.
Anyone else still on 2017.4 that have experienced something similar?

Cheers,
Kristoffer
