iOS 13.4 was released the other day for iPhone, iPad, iPod Touch, but unfortunately it has a dangerous one that the Apple company has not solved in a rather strange way, and this even though it calls into question all its praises regarding the security of the products that sell them.
iOS 13.4, like iOS 13.3.1, has a problem due to which the traffic made through VPN connections is not fully encrypted, so one of the main reasons why some people use networks of this kind in the first place disappears.
iOS 13.4 has a problem that was discovered at the end of 2019, so it's not exactly something new, but even in these conditions Apple hasn't solved it, but the good part is that there is a solution, the a little temporary, to bring things back to normal.
iOS 13.4 can have the problem solved by connecting to a VPN, enabling Airplane Mode, then disabling this option, but it seems that the trick doesn't really work for everyone, so you just have to try and check your internet traffic to see if it's secure.
“Typically, when you connect to a virtual private network (VPN), your device's operating system closes all existing Internet connections and then re-establishes them through the VPN tunnel. A member of the Proton community discovered that in iOS 13.3.1, the operating system does not close existing connections. (The problem persists even in the latest version, 13.4.) Most connections are short-lived and will eventually be re-established through the VPN tunnel on their own. However, some are long-lived and can remain open for minutes to hours outside the VPN tunnel.”
iOS 13.4 will remain with the problem unsolved, but iOS 13.4.1 will be released at some point by Apple to solve the problem, but no one knows when this could happen for iDevice users people from all over the world.
