Hmm. It has been working for the past 3 weeks until this week! So someone must have updated ArcGIS Online to plug the hole! Really, I don't see why you do this, who cares if it is a web map or document link, or whatever.
I guess the real question here is that if it was working, why not now? I think the "future release functionality" was working fine until it was turned off.
Thanks for your help though. I appreciate your time troubleshooting.
