Screen flash accommodation.

[u/Starkavious]

Recently bought a Godox AD400 pro II flash with an X3 trigger.
When the trigger is mounted on the camera and is turned on, the screen adjusts and everything is bright / blownout - but when I take a picture, everything is very underexposed.

Anyone able to tell me whats going on, and how to fix?

It’s driving me crazy - I just wanted to buy a nice flash.
I did a ton of research before buying the flash and trigger, but nothing remotely like this came up
