"I reported this through the Android VRP. Apparently, it is not in their threat model." According to Netguard logs UID 1000 "Dynamic System" appears to try to use the tunnel in an earlier Android version Blocking UID 1000 connections, and blocking QUIC, has not caused any problems for me Yet another example of the relative lack of user control, privacy, etc. in corporate mobile OS Not to mention undesired "side effects" of default use of QUIC

Honestly not sure if Proton or anyone else can fix this client-side on Android. Stuff like this is why people end up moving the VPN to the router.

"PERMISSION_SYSTEM" meaning you can bypass the VPN, with no option to override from the user, looks broken by design to me.
