No 3D panning and distance attenuation when building to iOS from Unity

Hi! 3d panning and distance attenuation work great when previewing in Unity and when building for OSX, but when i build to iOS it doesnt work at all. Sound still plays but in a non-source-specific stereo.

Not seeing any redflags in the XCode build log.

I’m new to fmod so I’m not sure if i’ve missed a setting or something somewhere. I’ve been through the documentation, this forum and hunted around elsewhere, but no luck. Any help would be much appreciated!

fmod studio 2.00.11
Unity 2019.4.4
iphone 11 pro
ios 13.6

Are you getting any errors or warnings in the output log files?
