Crossposting from different feeds

So I decided to make a category for things cross-posted instead of sending everything I post to the different silos.

It isn’t working it seems, I wanted someone to look at the steps I took and let me know if I missed something.

  1. I created a category called “CrossPosts”
  2. I then created a feed to the URL of that category (https://www.timapple.com/categories/crossposts/feed.xml)
  3. I linked my siloed accounts to it.
  4. I made a filter that says every time #cw is in a post assign it to the CrossPost category.

At this point I think I’m done, but no luck getting them to show up. I did notice the default feed is a .json file instead of .XML , I don’t know if this makes a difference.

Thanks,
Tim
