I've gotten my focus tree set up with all the relationship branches and descriptions, but when I try and view them by changing /edit/[ID] to /view/[ID], neither the relationship branches nor the descriptions show up. Is this a problem with my focus tree or the website?

That's the website. /view/{id} is very basic and just for if someone tries to view your focus tree without having access to edit it.

I will probably have a look at changing this at some point in the future. But it isn't a priority right now.
