Hi all! I bought the Spark two days ago and was having all sorts of rc linking and wifi connection problems. After I solved them, I was getting Switch WLAN region message everytime I start DJI GO app. I hit back and hit go fly, not a big deal really, except if I hit OK accidentally, I must hard reset wifi on both rc and drone and relink them, which is very frustrating. So I've decided to go with NLD mod and their patched app. So far it works good after a short test. Any NLD users here? Is NLD mod and app reliable and safe? If someone is using it for a longer time, I would appreciate to hear the opinion and experience thoughts. Thank you in advance!
