Why on earth does this Web protection app continuously turn itself "off"? Every day I get notified that it is switched "off" and I have to go through a 4-step process to check it, and switch it "on" again. I've never once switched it off! What's the point of having it, when it's always turned off?

Worthless and beyond pathetic. When you try to set up monitoring, such as via email, you are required to check email for security code. But Microsoft decides to jerk you around and refresh the page every single time, forcing you to have to repeatedly start over, and consequently never accomplish anything. This app is trash.

No complaints except for the website protection is constantly shutting itself off, so I have to manually turn it back on at least twice a day, and their support "fixes" don't work. Since they obviously know it's a big, I would have thought they would eventually write better code, but I've dealt with this long enough to look for something less buggy.
