Hi Arruntus, the drone we're flying was purchased in January 2019 (3 weeks ago), our other 2 H520's were purchased around the same time last year. When this H520 arrived, it was updated to 1.5.x, it was re-calibrated etc. All of our drones are subject to a professional maintenance schedule. Our technician produced the screen to give an idea of what we're mapping and to show the settings and for no other reason. IF there were an issue with versions there would be hundreds of people with the same issue. All the planning for a survey has been done on the ST16S and not on the PC, we use that purely for general planning.
We are still at a loss to understand what is going on here.
