Hi everyone. I've been trying to research this for few days now but no luck. The DJI Go 4 app on my iphone x has not been connecting to my Spark, for some reason. The RC is connected, the green LED is on but the app is showing to be disconnected, says 'enter device'. I don't think it's the cable. I've seen one advice to turn off wifi before connecting and it seemed to work, it connected for few seconds but then disconnected again. Tried it again but it hasn't connected again. Tried it also on another iphone but same problem. Any ideas? Thank you.
