I noticed that categories are given global ID’s so if I use a category like “movies” it will have the same ID as yours has on your sites.
Share catergory lists between WordPress sites@davew It’s worth noting that this is only true on WordPress.com sites. WordPress.com is a single WordPress multisite installation with many many sites.o, hence why some elements are shared between every site on the network.
With that in mind, you cannot really assume that IDs will be the same for different sites in WordLand. Someone could have multiple self-hosted sites connected there, or a WordPress.com and a self-hosted site.
