new to flying, so I feel like an idiot asking what it means when my drone is telling me I have 3 more flights with this controller. I purchased a used drone from somebody on Craigslist, while I was visiting friends down southern Oregon. I was told I could fly my mavic air 2 with just my phone. Not the case so I bought a used controller and linked it to my drone. What happens when I have 0 flights left and how can I resolve issue
