Weird issue I've run into recently. Most things work fine, but occasionally from the switch from cellular to Wi-Fi back and forth, the mullvad app in the work profile gets stuck. And won't reconnect until I open it and hit the reconnect button manually. And has this fun error screen, "no servers match settings".
I think the app gets confused, when there's really bad internet, like being in an elevator or switching from Wi-Fi to cellular, can't get the server list, and just stops.
I've only noticed this on the work profile, not the main profile, in graphene OS latest version
You're running two copies of the app, and the phone only has one connection, just run it from your main profile, there's no advantage or addl security to running it from the work profile.
The advantage of running mullvad VPN from the work profile is my work profile internet traffic goes over the vpn with a different end point then the main profile.
Sadly if I don't run a VPN in my work profile then the work profile traffic just goes out without a VPN over the clearnet.
