Oculus spatial reverb not working?

Hi - I set up my Unity project in FMOD and everything works as it should, including the Oculus spatializer plugin, but I haven’t had any luck with the Oculus spatial reverb plugin. I tried to put it on the Master track, but even if I turn all the knobs around, it produces no effect. I followed these instructions but no luck. https://developer.oculus.com/documentation/audiosdk/latest/concepts/osp-fmod-reverb/

From my tests the Oculus reverb plugin is working, although it’s settings do seem a bit fiddly. It would be best to ask this question on the Oculus forums and see what settings are best and what kind of reverb to expect.
