Even though I'm not planning on switching back to MKReverseGeocoder, I'm interested to see how long it'll take Apple and Google to fix it. This forum was very helpful to me in pinpointing the issue as a time-of-day problem; otherwise, I'm not sure how long it would have taken me to figure it out.
You can see my
blog post on my new app, which uses MapKit; I reference this forum for helping me figure out what was going on.
