Just a quick suggestion / tip. The large "here's how it works" pop-up over the On/Off button is very annoying. We all know how a VPN works or we would not be paying for one via a subscription!
Just to advise - and perhaps it helps - I do not see that issue on my Windows 10.
Agreed sounds like a Windows 11 / AVG relationship somewhere

Annoying pop-up that blocks On/Off button!
I have already done that a few times. It's simply an oversight by the software developers. Please let them know. If it helps, the pop-up ONLY happens on desktop program and NOT on the mobile App.
Thank you for sharing the screenshots, Tom.
Again, we're sorry for the inconvenience this has caused you.
Could you let us know whether the "Here's how it works" window is being displayed constantly or only when you move the cursor over AVG Secure VPN User Interface?
Awaiting your response.
Appreciate your efforts in notifying this to us, Tom.
We'll forward this to our senior level support to notify the developers.
Please wait for a reply from them. Thank you in advance!
