I bought this spark that I have over a year ago from a friend who has several drones. This thing is terrible. The first issue I have is that the camera loses connection with the drone about 50% of the time. I can still fly it but I have no video on my phone. It's hit or miss on whether or not I can actually use my drone for what I want to. The second issue is the active track. I try to track my 4 wheeler, boat, lawn mower and myself on a bike. It'll track for a minute if I'm lucky but then just quit for no reason. If it doesn't quit, It'll just fly over top of the object and lose it. The last update for the Spark on their website is from 2017. It's up to date on firmware according to the DJI Assistant 2 when I hook it up to my computer. I use the DJI Go 4 app on my Iphone. I've called DJI and they've told me to send it in for repairs but I have no idea how much they want to charge for something like this or if it's something with the app or I'm doing. Any ideas?
