Thanks Jan, I was able to get the latest Unity gRPC package to work with Oculus Quest (which does run on Android). There's just a minor modification to the package that is needed. You need to place all the DLLs in the lowest level folder, or Unity won't find them. This approach works on Windows and Android, at least. I haven't tested the other platforms. It might be worth exploring if this approach is broadly applicable for Unity and changing the distro accordingly. I found the workaround on another forum, but I can't find it right now to properly attribute.
