I have a maximum altitude of 50 meters and distance limit of 100 meters and I have not found a way to change them. Both numbers are in grey, as in you can't change them. I am however able to change the RTH altitude. I am not in beginners mode. Even in Litchi, I am not able to change the maximum altitude (there is no current number there, but I can't get in the box to change the number as I can in the RTH height box). Any ideas on how to increase those maximums?

Are in or near an NFZ? Check the geo map in the app. Flights are restricted to those limits if you are.

Are you just using your phone?

Are you in beginner mode?

He already said he wasn't in beginner mode in his original post.

Hi, we're sorry for the troubles that it caused. Would it be possible if you could verify to us if you were using a remote controller or not?  Would it be possible if you could provide us the screenshot of the settings? Please keep us posted on the latest progress.
