So I bought this mini 3 pro recently used. It is giving problems while connecting to the RC. I have RCN1. It shows low signal to moderate and would disconnect right after even if I'm right next to it. I have tried it at 3 different locations. Open fields too. But same issue. I have another RC-N1 from my mini 2 and it does the same with that. Sometimes it would connect and fly properly but would start to drop signal and then disconnect mid flight.

Has anybody else faced the same problem and have a solution for this?
