Our latest OS release that’s currently in the Beta channel implements a new feature for blocking DNS leaks by third party VPN service app implementations which were discovered by our community:

https://github.com/GrapheneOS/os-issue-tracker/issues/3442

The good news is this does successfully block these leaks.

The bad news is that we currently don’t feel comfortable moving this to the Stable channel due to a few reports of compatibility issues with @protonvpn’s app. Doesn’t appear to cause issues with any other VPN app after two days of public testing so it’s likely a @protonvpn bug.

We’ll give it another couple days of testing. Unless our users find an issue with another VPN app, we’ll likely ship this to the Stable channel instead of cancelling the current change. We can’t hold back an important improvement based on a single app which appears to be buggy.
