When I first tried the app it said connecting and then went to demo. Sad for a second.
Closed app and reopened and it said connecting and then a popup came up and asked what I wanted to do when this app is used or something like that. Checked a box and said OK and then it connected. Has connected 1st time every time since then.
If the HW is getting power its trying, maybe give it another try and see if there's a popup hidden on another page or something?
