On Mojave & earlier our NE VPN works fine. On Catalina the VPN starts, and traffic is being tunneled, but the
sendProviderMessage:messageData:returnErr:ResponseHandler:
method isn't working.- I don't get back an error on the call
- I do get back nil for the data in the response handler
- I don't see a call to the extension's
handleAppMessage:completionHandler:
entry point.Has anyone else been seeing this? I haven't seen anything from Apple yet about changes to the NE framework.
