Hype Reflect doesn’t work on my Hype Pro, im sure that my iOS device is on the same WI-FI network as my mac.
Can you make sure that you’ve upgraded both your Mac and your iOS device to the latest versions of Yosemite + iOS release 8.3?
Here’s other things to try: http://tumult.com/hype/documentation/3.0/#hype-reflect-faq
If that doesn’t work, can you let me know a little more about your wifi network? If you’re using a managed network, make sure you are able to connect directly to other devices.
