Today flying over a reservoir in the middle of nowhere I wasn’t able to reach more than 1,8km from the home point although I have been flying at 120m high. The RC symbol showing the reception quality changed to orange and a bad signal message appeared .I fly with an iPhone 8 Plus 64Gb and I have just installed the last firmware in both the AC and the App (IOS 1.1.5) . Has anybody a similar issue? Any suggestions ? Should I downgrade to the previous firmware in the AC?. Thanks and regards .
