format_value doesn’t apply filters based on the field’s key or name like
I think that’s a good question. My gut feeling is because ACF only formats values based on the field type. Maybe it is an oversight. I will submit this to the developer and see what he has to say.
Thanks for the question.
I agree, this filter would be very useful if it were target-able to a specific field.
I’ll add this to my to-do and add it to the next version!
