Just like the photos, if you use Phantom 4 Advanced to take pictures, you may find that you lost some photos in the pre-planned flights. You can find out at the track map of P4A, while another is ok using Phantom 4.
I do not know why? Likely, some bugs exist in Dronedeploy.
Could DD figure it out as soon as possible.
I know, DD just started to support Phantom 4 Advanced, two months ago, DD even can not connect this device.
I wish, this simple error will be cut off soon.
best wishes for all
