Thanks, yeah, that seems to work. I changed my pipeline code to not send any title metadata to ProGet, which returned that field in the UI to its original behavior. I also found that rebuilding an existing package, and sent to ProGet with the updated pipeline, has the same effect.

You should have access now! Let me know if not :)

Thanks for the detailed information, that's very interesting and a great assessment. We wouldn't have found this using all of these variables, especially the different Windows desktop version I suspect this might be a bug in the underlying libraries? We just use an HttpListener and a HttpWorkerRequest, both which should handle all of this, in the simplest way possible. I'll ask around and see if anyone knows. But I guess, at least you found a work-around which I'm glad to hear!
