Iphone 6s and IPad Pro not connecting to controller but 2 Iphone 6's connect easily

[cwamd]

I just bought a new Mavik Pro with fly more package on July 25 at OshKosh. My Iphone 6s and IPad Pro will not connect to the controller. However, my son's both have Iphone 6's not plus or S. Their phones connect easily. I have tried every suggestion that I have found on the web to no avail. Does anyone have a fix that works for this problem? Thanks!
