I can confirm that this may be device-specific.
I had this problem on Sony XZ2 Compact and tried to solve it for 2 hours. Then I ran it on Google Pixel 1 and it worked immediately.
Personal conclusion: use Google VR on Daydream devices. The XZ2 is not a Daydream device. Though I’ve tried some VR games on the XZ2 and they do work… With Google VR UI (the settings icon on top right). Oh well…
P.S. I am using 4.24 and haven’t tried downgrading or copying folders etc.
