Home Assistant App not setting Client IP address correctly

Last working Home Assistant release (if known):

Description of problem, include YAML if issue is related to notifications:
I'm trying to access home assistant over VPN and this works fine in the browser but not in the app.
My reverse proxy has a block-list in place to only allow local traffic to home assistant.
In the reverse proxy logs I see the public IP of my phone in the logs when connected via vpn. In the firewall I can confirm that the majority of the traffic is actually coming from the local vpn IP address.
However I can also see that the App is managing to bypass my full tunnel wireguard vpn and I'm seeing a few requests on the firewall come directly from my phone IP to the reverse proxy.

If I force-on the vpn in android OS settings and block all other connectivity, the app fails to start entirely which is not confidence inspiring.

Do you see traffic for specific endpoints 'bypassing' your VPN?

The app does not have any specific handling for this, it should follow your default network interface. My thought would be that it is for operations that are already running or otherwise pending/active connections.
