Thanks Rick. My problem was with the instructions - they said to "expand" the screen profile, which I interpret as "click the plus sign." I did that over and over and over again, and still didn't see what I needed. When I finally thought to double-click it, I got in.
For what it's worth, I would have interpreted it the same way you did!
Success in publishing. However...I carefully set all the conditional tags for "NOT External" before I published Multiscreen HTML5 to the external site. I pulled it up on my PC (presumably the Desktop Screen Profile), and the conditional tags DID NOT block the content. However, they worked on my IPhone. I confirmed that the conditional tags were in place for the Desktop screen profile, as well as all the others.
I don't have an Android, IPad or a Kindle Fire, so I can't test everything and confirm that the conditional tags worked. But in the meantime, do you know what may have caused this to happen with the PC version?
I also viewed the content on my IPhone before and after the upload, and didn't notice a difference. What actually changes, when you optimize for handheld devices? What should I be looking for?
