Thanks for your response on this. (BTW - looks like the "Notification" option isn't functional either... hence why I'm only responding to you now!).
It appears as you've stated (re: the project and response). Kind of a bummer. While I realize the challenges of communities, volunteerism, etc., some predictable involvement from folks would be nice. It appears to be all over the map (pun may be intended, I suppose).
Re: the technical issue: I DO have one data point and it's rendering. So, I'm not exactly sure what this could be. At some point (hesitantly, BTW), I'm starting to think that just using the GoogleAPI directly may be more productive. Less overhead and predictable behavior and dev support.
To be clear, I'm a huge fan of DNN. However, it would be great to get a little more predictability in just basic support.
Thanks again for your response - much appreciated.
