Don't upload waypoints - DroneDeply in DJI Phantom 4 with iPhone 5s

I’m trying to fly a plan, but I get this message about uploading waypoints.

Everything is fine with the plan, the drone is ok and ready to fly. I have a good internet conection, also.

Why is this happening?
What will happen if I hit “continue anyway”? Can I just do that and will it fly normally?

Thanks!

If you get Waypoint Errors you might want to try some of these:

Recycle power on the drone and controller.
Close the DD app and connect the drone in the DJI app to make sure it has 7 or more satellites available to make sure it knows where it is at and can get a home point.
Close the DJI app.
Open the Drone Deploy app and copy the flight plan using the three dots to the right of the name. Use the new plan.
If you still get the error, try changing the Flight Direction by a few degrees.
Uninstall and reinstalling the DD app.
Turn the mobile device off and back on to clear out possible conflicts.

Hopefully the first few of these will solve your problem.
