If I try to publish a post while a required field is empty, WordPress shows a warning. But it does not show which field is missing, nor can I see which field group it is.
So, I have to open all field groups until I find one with a field that is marked red.
Is it possible for me (or you, as a feature request) to mark the field group with the field that needs to be filled out? That saves a lot of time for editors.
It looks like the required field is located in a collapsed group or a tab. So the warning text does not display in the wrapper element. I will inform the development team to consider supporting this case in future updates.
