I accidentaly crashed my dji mavic air into a brick wall at 28mph, and ever since the backward sensors will not calibrate. I have tried on the app but when i go to do it in the app the instructions telling me to do it never pops up. But when i do it on my pc both the sensors show up at the bottom and work on all the boxes but at the end it says calabration failed and i am doing it on acurved monitor. But the weirdest part is when i take it off they work for about 5 seconds but they are VERY unaccurate then the the error message shows.
