The direction Photoshop was going with the new file exporter is awesome, but please, let us record actions with it in the action panel! for Photoshop CC 2015 it says it is "work in progress". Any news? (Using CC 2019 here) Looking forward to this. :)
this is a question we would all like answered. It's been many years since the introduction of Export As and we're still unable to put it in an action. I've just gone and retested since it's been a while and yes, still not working. Out of curiosity, i tried using the Insert Menu item command in the action and it returned Select <unknown> Menu Item.
