Ok great. Thanks for your support John!
Thats strange. Did you also got it working what my solution was?
Awesome John, this example pointed me into the right direction.
Strangely and after experimenting with the long code this example uses, I was able to just add the first ACF sub page as a ‘show_in_menu’ value to the CPT, and it worked without anything else. Why this works – I don’t really know.
Thanks a lot!
Seems to work for me, thanks for the fast response!
