Hey, Derrick - I, too, also use multiple tags and categories in each blog post, but when I include a summary block at the end of the blog to feature similar content, I'm no longer to select or enter multiple tags and categories (like I can in the actual blog post). I can select the page (my blog) and only one category (metadata) and one tag (metadata) instead of multiple categories and tags like I could before the update. That's what I'm trying to figure out - why that's changed in the summary block.
Maybe I don't understand what you mean by "in a 7.0 summary pulling from my blog ..."?
