I am flying P3P with latest app version. All proceeds well with preflight checklist except for uploading mission to drone. It appears to attempt it (hourglass icon) but then X's out. I attempted numerous cancels and re-start and rebooting entirely. No dice. I see with the new app release it states:
Sometimes the mission cannot be uploaded (in the preflight checklist). Solution: Hit "cancel" and to start the mission again.
Again, I've attempted this multiple times. Can anyone else or Pix4D speak to this issue and progress on correcting?
