Thank you. We kind of figured that but wondered why it stopped to ask enter activation code, then on a second try it went right by that step but got locked on activating and we were getting the magnetic interference and Check App messages on controller. The compass probably needs calibration but we couldn't get to a place where we could calibrate compass because we could never get by that hangup at activation. I sent an email to DJI Support, maybe sometime they'll get back to me. Thanks for you help, though.
