Hi, I currently have two CPTs connect to each other, however I would like to add some additional meta that goes specifically with the relationship. Here's a quick fictional use case so maybe I can explain better.
Let's say we have a CPT crypto platform and a CPT payment method. Currently, the crypto platforms are connected to one more payment method. For each relation, we need to add a minimum & deposit.
In the above example, what we're trying to achieve is to add the min and max deposit meta for each relationship. I looked around but couldn't find much, even a post requesting something similar from what I can understand but it seems it wasn't updated in quite some time - Link.
