So I've gone in and tried to reproduce this exactly. I did have the
banner in the collection it was referencing before as well. But for
testing sake I created a new collection with a really long name, a new
article with a really long name and put the navto banner in the
collection pointing to that article. I did not publish the new
collection or the new article. Using only preflight, I view my new
collection and tap the banner and it goes right where I expect it to go.
Not that this should matte...
