"Send notifications to current user", "Block connections without VPN" question

deleted

Only 3 profiles (owner profile and 2 user profiles) can run simultaneously. If 3 profiles are running, 2 in the background, and all 3 profiles have a VPN "running" with "Always-on VPN" and "Block connections without VPN" enabled, and only the currently accessed profile's VPN connection can operate, are the other 2 profiles' VPNs blocked, preventing clear net leaks? If this is the case, this would conflict with the "Send notifications to current user" feature if the 2 profiles' VPNs are blocked from transmitting data, correct?

Where did you get this from?

My understanding is that if a profile is running in the background, its VPN is also running.

Probably9857 Because Android and GrapheneOS only support 1 VPN connection in a profile at a time, hence this would apply to different user profiles. As this appears to not be the matter (here and here), then 3 profiles running simultaneously can have 3 VPN connections simultaneously, or only 2 VPN connections can run simultaneously due to current software memory limits?

Since owner profile always count towards this limit, it's effectively 2 profiles plus owner that can stay active at the same time (i.e. no "Unlock with passcode after restarting your phone"), which is why VPN was kept getting shut down once I open a third profile. https://discuss.grapheneos.org/d/1083-keep-vpn-on-on-inactive-profile/8

No, it applies to each individual profile. There is no restriction to the number of VPNs running across multiple profiles, except for the restriction that only 3 profiles can be running at the same time.

Yes.

I'm not sure what you see in that link that make you think only 2 simultaneous VPN connections.

You can have 1 VPN in the owner profile + 1 VPN in each of the active secondary profiles. Since there is a limit on the number of active profiles, this effectively limits you to 3 VPNs. But the limit is on profiles, not VPNs per se.

Private spaces will increase this to 4 active VPNs (presumably).

As the user "open a third profile", the "VPN was kept getting shut down once I open a third profile", therefore only 2 VPN connections can run simultaneously.

deleted "VPN was kept getting shut down once I open a third profile"

I read that as "third non-owner profile."
