I have a Dji RC2 controller that I use in conjunction with a Mini 5 Pro.
The problem I have been having started after one of those last updates in July, if I take any video with the drone and I try to preview them I get a blank screen that after a few seconds brings me back to the connect to the drone screen. But if I have taken pics it allows me to view them, just not the videos. Really frustrating as sometime if I have done a really crappy one I delete it and start again.
For the record I have a MicroSD card high speed / and top quality 256Gb and it has been formatted and let me repeat that before that (explicit 
) update I was able to review my videos no prob.
If you know a fix please let me know thanks in advance.
