Hello, I'm running 21.9.2491 and it's causing issues with my internet connection. The WiFi drops out or becomes completely unusable about every 10-15 minutes. I turned all shields off and then back on one by one and discovered Web Shield is the culprit. Right now I have it disabled indefinitely and haven't had any issues.
And there's been twice that the UI won't display. After popping up from the tray, it simply states that while I'm protected, there's an issue that requires a reboot to repair. Not sure if that's related, although the UI does slow way down concurrent with the WiFi issues.
