Hello. I bought a used P3P about a month ago. Love it and so far no problems. Today I was planning to fly before work. When I powered it on the RC would not connect to the AC. I power cycled both a few times and after the 3rd try they connected. I reloaded the DJI Go app on my iPad air 2 and all seemed good. The current status says "firmware upgrade required". The flight controller serial number was blank. Since then it has populated the serial number for it. Current firmware: AC - 1.9.60, RC - 1.8.0 and the DJI Go app - 3.1.0. Little worried and not going to fly it til I am sure it's stable. I guess I won't be "messing" with our cattle today. Any thoughts would be great.
