Parece que ya somos varios, en mi caso actualice Android 10 en un cel Galaxy Note 10+ y efectivamente, dejo de funcionar la app DJI Fly. Alguien conoce la solución, por favor. Una me imagino es regresar al celular a la veersión Android 9 o esperar la actualización de DJI Fly???

Ya esta funcionando la actualizacion DJI Fly, muchisimas gracias a los que hicieron esto posible, saludos... The DJI Fly update is already in operation, thanks to those who made this possible, greetings...

Finally got update to version 1.0.6. App is working great! Thanx DJI.
