While looking at my report on healthy drones, I noticed I have numerous minor signal errors on almost every flight. I'm not sure of the severity of these multiple error and don't know if I should be concerned. Some of the errors were when I knew I was nearing the end of my signal, but most of the time I had no idea there were any issues at all. The signal map showed green on most of the times. Is this something to worry about, or not?
