Figured out... something.
I guess I now have to "officially" enable Street View mode rather than simply placing a location marker.
I was getting into Street View by clicking on a roadway, then clicking the popup it gave for that location marker. If Street View data was available, the popup would have a thumbnail of the Street View image for that location. That way doesn't seem to work any more. Now, I have to enable Street View mode by clicking on Browse Street View Images (the yellow stick figure in the lower right corner). When I do that, it highlights all roadways with Street View images and seems to work as usual from there.
It's irritating that I can't do the simple single-click access any more. Yea, progress.
