I did...it was terrible. I then had to hack the app to find 2.8.1 again. I then downloaded the previous one and now it works great. If you search the DJI forums, some have problems some do not. I was a unlucky one and had problems. I have never had problems updating my apps before. 2.8.1 will be on my ipads for some time now.
Sure.. i would get the weak video signal at 50 feet, but the bars on the app still showed full strength. Green lines, serious lag and even black screens. At one point i was coming back to land since it was so bad and the app just quit. I looked up and the bird was still there. I then rolled back to 2.8.1 and put it back in the air...ROCK solid. not a single problem...
