I’m sorry to see this. The issue you are experiencing is something that all apps that use the DJI SDK will have an issue with. Sadly the communication between the SDK and the drone is not as solid as we would hope. Because of this, it’s difficult to get the same results every time. We are working with DJI to fix the issue but it will take some time.
Because you have flown this area of interest in the past, we could be seeing you might have encountered what’s called a TFR (Temporary Flight Restriction). I’m curious if you checked the NOTAMs that day and if there were any flight restrictions in the area. We are working to resolve the issue. I apologize for the inconvenience.
