Godox v850ii and X2T trigger not syncing with A7IV

The A7IV is meant to have a flash sync speed of 1/250th, but using a Godox X2T trigger (for Sony) and a Godox V850ii I get sync failures at anything faster than 1/160th. Does anyone have any ideas for what I should check?

  • The camera recognizes that a flash trigger is attached
  • I'm using the mechanical shutter and electronic front curtain is turned off
  • HSS works as far as I can tell, the problem comes when using the flash in normal mode
  • I'm using AF-C, single shot burst
  • The flash mode is set to "Fill flash"
  • It's my first time using the trigger, but since it works below 1/160th and in HSS I don't think I've made any mistakes setting it up.
