Mission "completed" immediately after takeoff

I was flying a number of multi-battery missions last week and on several launches after a battery change I would get an immediate notification that the mission was complete, when the drone had just taken off. Drone is a P3P running the latest firmware, iPad Mini 4 running the latest app version.

Hi Tony, sorry to hear this.

This usually means the P3P was having a hard time communicating with your mobile device. Could you provide your user email address, so I can check your logs?

Thank you,
