Pushbullet Service not working on 10.4.1.0 (5514121, 2016041101) on OS X?

I am trying to use the Pushbullet Service in Mathematica and it is not working. Following the examples in documentation: (Pushbullet—Wolfram Documentation), seems to connect okay (although it does not retain the API key when you request it to). But none of the remaining code in the example executes. I am able to use other Services (example: Twitter) fine with Mathematica. I am able to execute the Pushbullet API fine with the same API key and the curl api commands as documented by Pushbullet.

Has anyone tried Pushbullet under 10.4.1?

Thanks,

Dave
