Hello,
I have decided to use Piklist for a project instead of ACF, specifically for the post to post relationship capabilities but using the built in Piklist Demos, the relationship function is not working as expected.
When creating a new Demo Post, in the Relate > Advanced Tab, I can create new related posts from using the Related Posts form, I can create as many as I want. However if I then publish and edit the Demo Post, I cannot add any more related posts, only edit the ones that already exist.
As an aside, I also experienced this issue using my own CPT, so I then tested it with the built in demos.
Thanks
