Why can’t I receive any event? / Why can’t I click on system overlay?

This symptom happens once you reload scene with a persistent WaveVR prefab. For example, writting

DontDestroyOnLoad(transform.parent);

in WaveVR_Render, or any other equivalents.

We will suggest you to try

DontDestroyOnLoad(transform.parent);
DontDestroyOnLoad(WaveVR_Init.Instance.gameObject);

to avoid the problems.
