,
I created a new project and imported VIU and the Oculus SDK and it runs on the Oculus Go. However this doesn't make the plugin very useful to build a full project on multiple platforms.
In answer to your previous questions:
1. I had only Oculus Go checked.
2. Yes, I had removed the WaveVR SDK plugins folder.
Is dll switching something that you are/would consider adding in a future version of VIU? I think it would be an extremly useful feature.
