Since the recent firmware update my mini2 will go no further than 350 meters   , i bought this drone because of the great specs and the range was the main reason,  
Is anyone else in the UK having this issue or has had this issue

Hello there. I am sorry for the trouble this has caused and thank you for reaching out. May we please know if you had receive any error message on the DJI Fly application when this happened and may we also please know what is the model of the mobile device that you are using please? In addition, can you please fly your DJI Mini 2 to a different location with less interference to see if the issue will still persist and please make sure that the antennas are pointed toward the aircraft for optimal transmission as well. Thank you.

Im in the UK and haven't had any issues since the latest firmware.   What I did notice is that the Fly App will show a warning for interference if when there isnt any.
