Connect Wwise to Quest 2 game?

Hi,

We've got a UE4.26 game up and running on the Quest 2 with Wwise 2021.1. All the audio is working fine but we can't seem to get Wwise to connect to the game running on the Q2. It can connect just fine when running inside the editor on PC. Has anyone gotten this working?

I've tried checking everything I can -- it's a development build, I've confirmed that the Wwise communication library is initialized successfully and the UDP port settings match, etc. I'm wondering if there's some reason this can't work on the Q2 or if there's just some other setting I'm missing somewhere.

Thanks for any help!
