We seem to be having an issue with our iphones and wifi calls being blocked while using the Avast VPN and using wifi calling. Our ISP is Xfinity/Comcast. Is there a way around this issue to allow us to use a VPN with Xfinity/Comcast? Our cell phone provider is Verizon. On my phone, I have to go to settings and turn VPN off, then go to General-VPN & Device Management, click on VPN, then make sure it’s not connected. The Device VPN is Avast Web Protection. I’ve gone to that and deselected Connect On Demand.
