I have been getting notification that my NordVPN needs to be updated. When I check my phone to see if rhe update has been completed, I see that the process is hung and a message next to the icon sys: waiting for wi-fi connection! My phone is connected to my home wi-fi, so I don't understand... When I bypass this and want to download the updated version it says I might be charged for daya usage! What is going on? Is my app gping to be updated or what?
