After using the Packet Tunnel Provider to create a VPN and setting the includedRoutes to defaultRoute, not only the DNS information of the "en" port cannot be obtained Monitoring of network switching will also fail This has bothered us for a long time

@MobileTen I get the following output by iterating through the layers in different versions On macOS 10.12.4, the output is: (     "<CAGradientLayer: 0x60800002ff00>" ) On macOS 12.4, the output is: (     "<CAGradientLayer: 0x6000003d05c0>",     "<NSTextLayer: 0x600000d0ddd0>" ) Therefore, I suspect that the title does not exist as a layer in macOS10.12.4
