Actually it tried to jump from RC to my home router, I loosed connection to the RC on day 1, that's why I used the OTG right after and never looked back.
As for
@matty4 I recommend using OTG cable specially made for Dji drones with Micro USB to USB C like this one

Some OTG are one way data so they won't work but these cables made for drones work perfectly
