@jlock6000 this is quite old but yes.

The ACF field is on the Taxonomy and it is a Post Object (return Object and not ID)

@froutsis Thanks a lot for getting back to me so quickly. Much appreciated!

I still have some problems getting it to work. I see that you do freelance work. Would you be interested in taking on this task and fixing it on my project? If so, please get in touch with me at janus@digitalist.dk

Thanks
