Not shocking. Their VPN app sucked ass. A) it randomly disconnected several times a day, and B) it had no "kill switch" option which would block all traffic when the VPN went down. So my connection was frequently unprotected throughout the day.
I can’t remember, but didn’t it require the Android Google One app to do VPN on Chromebooks? I remember it being hard to setup, but perhaps I’m misremembering my journey through dodgy VPN clients.
Not sure. I only used it on Windows
