Er? Android supports multiple VPNs at the same time on the same user profile? Since when exactly?

I tried it once but had some issues where it was hard to get the Tailscale DNS to play nicely with my container setup. It's been a couple of years so I may be misremembering, but I want to say the issue was that it only would resolve names to the IP of the host, not the containers themselves. That could've changed by now, of course.
