Lots of issues with flash transmitters with this firmware.
I had two shoots with the A7V that involved off camera flash with Godox triggers.
First shoot was fast paced, lasted 25 minutes, and there was maybe one minute at most in between shots. There was about 150 shots in 25 minutes. No issues.
Second shoot was in a studio where we had mini sessions and when there was 2-5 minutes between shoots. My Godox X2T was constantly disconnecting from my camera that required pulling it from the hotshoe and remounting it. I switched to my Godox V480, set it up as a transmitter, and the issues persisted. Fortunately with the V480 I could just power it down, power it back up, and the transmitter worked again.
Through all of this the camera indicated the flash was connected, but the flash would not fire.
I set the camera and the flash to not power down/sleep, but the issues persisted.
