The platform soundbank subfolder within the Wwise project could not be found.

Question

Hi - I've connected my Wwise project to Unity and I keep receiving the following error in Unity: The platform soundbank subfolder within the Wwise project could not be found.

I've checked the Wwise settings in Unity and the soundbanks path is in the Streaming Assets>GeneratedSoundBanks path which seems to be correct.  In Wwise, the project has separate Windows and Mac subfolders allocated, so these don't need to be added. I have tried moving the folders around and adding a Mac subfolder to the streaming assets location but this has not worked. Any advice on how to fix this would be great, thanks!
