Same problem here for this new member. I deleted my Old GoApp and downloaded the GoApp for I1, Osmo, etc, thinking it would be another GoApp sans 4. When I opened it, the logo showed it was Go App 4! Thought I dl the wrong one. But decided I'd try it first and it worked. At least I think it did as I couldn't test fly the bird in the dark, but I noticed the altitude limit has now self-populated with 120m. Before it was zero. Adding 120m up to 500m made no difference. I am hoping tomorrow at my RC clubs airfield it will allow me to rise higher than 98 feet. I will be a bit embarrassed if it doesn't but I can get some good vids of my brother pilots flying their rc craft at lower altitudes, But I am hopeful the 98 ft limit is no longer there. Next to useless for much else.
I have an I1 Pro I haven't flown in a year since I got the I1 V2.0. I will be a bit wiser if DJI forces me to do the update on my Pro as well. Of course, no more unlimited altitude flights, but that never interested me anyway.
All my problems started after loading the new firmware. After several hours of hair pulling and google searching, the I1 was functioning again, albeit with the altitude limit.
Thank you Davidp and everyone who contributed. This is a great forum.
