Hi Chris, Related to usage of DTLS: how useful is a UDP version of the protocol in practice?
In the US, I know Verizon and Spring drop UDP from their 3G/4G networks. The datagram hits the server, but a response is not received by the client. That testing occurred last winter for me, and I doubt anything has changed recently. Do European network providers allow UDP traffic to a device? Or are the UDP use cases centered around Wifi?
