Is DJI O4 Air Unit Pro worse than it used to be?

I've been experiencing some weird problems with DJI O4 Air Unit Pro units in some of my #fpv quads recently, and as I've started to piece things together I've realised there's a common pattern to it. I've put this video together to try and make some sense of it. Below are some links to the some of the source information I've used for the making of this video: DJI Support Forum Thread: https://forum.dji.com/forum.php?mod=v...
