I run a Roon server on my desktop. When I run the mobile app it is able to find it on both iOS and Android devices, but not on my GrapheneOS device. App downloaded from the Aurora store.
I've tried with both my VPN on and off. I enabled local network connections in my VPN. I've changed the network settings to send device name as well as tried switching to "Use per-network randomized MAC". As for the app settings, I've given it full access to network and sensors, and enabled exploit protection compatibility mode... None of these things seem to have worked.
Any suggestions?
