hello,
I am having a similar issue as a lot of people on this website it seems. I am having issues with my mavic 2 pro connecting. I get different warnings such as, weak signal, adjust antennas, no video transmission, aricraft disconnected, no RC signal, etc.. I have updated all firmware on the RC, drone, and app. I have formatted my SD card, tried a new intelligent battery, I have up-to-date ios on the ipad mini and iphone x that I use and I have tried mulitple cables, even brand new cables. I have done the vision calibration, IMU calibration and have restarted and reconnected the RC multiple times.

I have flown this drone maybe 4 times. This issue didn't occur the first flight, but every flight since then has done this.

What is the fix?? Please read everything I have tried before making suggestions to minimize comments. thank you
