I’m seeking clarification on why iOS prioritizes IPv6 when both IPv4 and IPv6 are available. Does iOS always default to using IPv6 in such scenarios? Is this happening by design as Apple developer docs never explicitly state the prioritization rules. This might explain us why the issue doesn’t occur as frequently in IPv4-only environments

We’ve noticed that in iOS 18, the "Deactivate Configuration" button within the Per-App VPN settings immediately disables the VPN for selected apps without any confirmation prompt. This can be problematic for users, as there is no warning or verification before the action is taken, which may lead to unintended disruptions in VPN connectivity. We haven’t found any relevant documentation on Apple’s developer website addressing this behavior. Any insights or suggestions would be greatly appreciated and if we can have documentation to disable this button using MDM profile it will be great

In our Device Configuration Policy (MDM Policy) We have Excluded Domains that should prevent VPN traffic for that domain but it's not working for iOS 17.5.1 but were working before!
