I'm fairly new to drones. In April'18, I started flying a Mavic Air with my Nexus 5/Android-6/Go-4 v. 4.2.8, and no flight problems.
Now, I with the updated Go-4 App v. 4.2.12 , while the M-Air (now V.01.00.0400, R-C V.01.0100) is flying, I get a message on Go-4; "Go-4 isn't responding, want to Quit or Wait?" I ignore the message and land the M-Air. This has happened several times.
I'm open to any suggestions on what to do next.
