Weird Reboot/Restart and VPN settings gone then back

This is the 1st time I have had this happen in my 3 weeks with SFOS.

Today I was in fb messenger if I remember right and suddenly the screen went black. None of the buttons did anyting for about 10 seconds then the screen back on but everything was closed.

It seems like lipstick restarted rather than a full reboot. Never saw the SFOS start screen.

Noticed my VPN wasn’t running so I went to settings and there were not vpn settings to start. Closed settings and reopened, still nothing.

I finished what I was the in the middle of when this started and went back to settings and all my vpn settings were back and working.

So…what happened guys??

Everything is working just fine since.
