Besides right location on the map, ensure right orientation of your drone direction on the map.
This is where most flyaways can occur when orientation on the ground doesn’t match how it appears on the map.
For precision landing to be set, you then need to take the Mavic straight up ~ 10m and get that screen notification.
Precision landing is optional though, you can fly ok without that set, but it’s nice for RTH almost landing on the exact spot and orientation it took off from.
