Not that I don’t like the specs of this newcomer but when the time comes that I want to upgrade I will look at another DJI drone. The Tello so far has been perfect for my level of experience, if only it had a gimbal
On your Tello App go to settings, than more. Than select the tree Dots.
You will find a place where you can chat with Tello. I tried it and got in contact with Tello in minutes
Good luck
True you don’t but you will have issues flying using your controller as you won’t be able to attach to the controller.
At first I flew my Tello using only my iPhone but once I started using my controller I was hooked.
