VPN not working in Avast Security and Privacy App in iPad

When I turn the VPN on, it disables the wifi and thus no VPN connection is made. When I turn off the VPN, the wifi is enabled again.

I had the same issue when I tried using the VPN in Norton 360 app for iPad. Norton customer support would not resolve the issue so I had the purchase refunded.

Update: I just found out that Norton owns Avast.
