So I have been using my tello drone just fine without any issues, even up until a couple weeks ago. However, today I attempted to fly it, and it said that it needed to update firmware, and I attempted to so so, but whenever I did it would stick on this screen:
I have attempted to delete and reinstall the app, but nothing I have done will make the app update. A friend downloaded the app and was able to fly the drone without issues, but I haven't been able to (I have Android, he had an iPhone). Any help would be much appreciated.
