If the apple documentation says it does, that would seem like an obvious bug, but I'm curious whether the apple docs do say that, or there's a general assumption of that being the case?

Oh, as I think of it, did you test the UI switch position or network traffic? I could believe the following behaviors:

* UI switch turns off, private relay continues to carry traffic

* UI switch stays on, private relay continues to carry traffic

* UI switch stays on, private relay does actually turn off

All seem like entirely plausible bug behaviors, and it would be nice to know which it was (UI off + iCPR on would seem to most overtly be a bug)

Does your VPN possibly not offer a default route?
