Totally invasiveNeeds web connection, complains all the time. Uninstalling.

HELPHelp Me please..The VPN feature, which was disconnected last year, still appears in the interface of my Microsoft Defender account app, despite no longer being functional. To resolve this, I had to completely delete the app from my device.
