I was writing a post to my publication and couldn't tag the Publishing niche. Is there any reason why I wouldn't be able to tag a particular niche? Is it because I own the niche? Or do you have a limit to the number of niches a publication can tag?
Publication posts are not treated any differently in terms of linking to niches. Every post can have up to three niches. It also does not matter who owns a niche. Perhaps you already had three niches applied to the post?
@Ted Whatever the issue was, it fixed itself.
