How are you now dealing with locations where you know the name of the city, state, and country but you don't know the county? (Some cities span several counties.) To date I've dealt with this by using the format "city, , state, country", leaving the county blank. The new system doesn't know how to deal with this. Here's an example:
Iowa City, , Iowa, USA
I can leave as is, of course, but then I can't take advantage of the hierarchical view.
If I put "Iowa City" alone in the place detail, then it appears at the county level with no indicator that it isn't a county. If I put "XXXX, Iowa City" in place detail, then Bing can't find it. Similarly, it cannot find "Iowa City, ?"
