Created a c# Console app as per https://learn.microsoft.com/en-us/azure/iot-hub/iot-hub-csharp-csharp-c2d#get-the-iot-hub-connection-string. It works OK with no errors. Have added some ack code to device upon reception of a CD Message and when Console app is set to DeliveryAcknowledgement.Full or PostiveOnly console app comes back with Success!

I have the exact same problem! It works in VSCode, but not in Azure IoT Explorer. Please fix it. It's a wonderful tool - except the bug.
