I think I have found a mistake in the Metabox Group plugin. Last month you built in a function to limit the maximum number of clones When adding this goes well. After adding you can add an infinite number of clones. If they are then removed again, the button will disappear too.
I'm not very clear about the bug. Do you mean that when adding max_clone, it still allows you to add infinite number of clones? And when you remove a clone, the "Add more" button disappear?
Yes and no 😉 When you add max_clone and make a new item with the max item of clones, save the item and then edit the item, it allows me to add infinite number of clones (the button shows when the max number of clones is reached).
