I downloaded a firmware update that now has created the most trouble connecting. It is super unreliable now. Immediately after updating, I lost control of the aircraft, and literally had to wait until the battery ran out and it landed automatically. It disabled the phone control completely. Then after charging the Tello, connecting to the phone did not work all day yesterday. I tried again this morning, and it worked once. Then when I shut it off and tried it again, it would not connect. I regret updating the firmware. Should have never done it. It was working fine before that. What can be done??? Anyone else having inexplicable connection problems?
