@david_legrand , just tested, I am able to receive. When you try to send, what are you seeing in the logs?  

@Gerry O'Rourke , we did find an issue, that I believe is resolved. Please let us know if that's not the case and you are still not seeing items get logged. 

Debug definitely should show logs. There is  a delay from the time the flow is triggered to when it gets fully logged. Checking a few minutes later and you still have nothing in your logs? 

The documentation pages have been updated with a new (fixed) URL. Please import again and reply if you are still having problem.
