I had a photoshoot las Saturday and I was using my Godox AD600 together my Sony A7iii and the Xpro transmitter. For some reason the Godox AD600 failed to fire many times, sometimes more than once in a row...basically the camera would take the photo every single time but the flash did not fire at times. It was very frustrating as it made me miss some really cool shots. Everything is up to date with the firmware, trigger was attached to the camera properly and the AD600 had a full battery. Any ideas on what might have caused this issue?
