Vivofit Junior Unable to complete request. Verify your connection and try again

I bought my son the Vivofit junior and have not been able to get it to pair to my iPhone. I go through the steps, it recognises the Vicodin, and appears to pair the device. It moves to a new screen saying Connected! at the top and a message saying “we just need to complete your child’s profile and device settings to finish” with a spinning pin wheel, but then comes up with an error saying “unable to complete request. Verify your connection and try again”

this is has been driving me nuts.

please please please help. ciq.forums.garmin.com/.../1460858.jpg
