Last week, we uploaded our mission's waypoints using DJI GO app. Our Inspire 1 set the waypoint mission fine, but then we had to land to replace the Intelligent Flight Battery. After replacing the battery, we flew to near the first waypoint in the mission and loaded it. It uploaded all the waypoints, but then we got a message that said "failed to start the mission" – or something like that. This is a step-by-step procedure of what we did: 1. Flew the mission to set the waypoints. 2. Saved the mission to favorites. 3. Flew to Home Point and replaced the battery. 4. Flew to within 10 feet of the first waypoint. 5. From Favorites highlighted and applied the mission. 6. Waypoints were successfully uploaded. 7. Applied and received “Warning – Failed to start mission” 8. Retried loading (successfully) and applying. Same failed to start notice. Has anyone had this happen before? Any suggestions on what could have caused it?"
