Oh wow... thanks... I did not know that there were other apps designed to work with the DJI Tello drone... amazing... thanks!Hello
Sometimes the apps don't work for all devices yet until they do updates and add devices to the list.
You may want to try this app and see if it helps you while you wait..... I found it to be great.
Best of luck (fingers crossed)
It is just a demo so you do not have to pay for it, And if it works for you, Great, They have a paid version on google play as well.
