Not working correctly

The app is not working correctly for me. I just purchased the camera and am trying to set it up with my phone. The app says that the camera needs the last seven numbers of the cameras sn as the Wi-Fi camera password. When you enter seven digits the join button is still grayed out. You get a blue "join" when you hit space but that doesnt work either. It must work for some but not for me and thats why Im leaving a negative and rating here and on Amazon and returning the camera. SPECS: IPHONE 6 PLUS (UPDATED SOFTWARE), BLACK YI ACTION CAMERA.
