Colin T. when you initiated the import - did you happen to notice any kind of error at all - it would have been a toast at the top right.
For me in my testing - it was because I still had the app drawer open and it said something to the effect of "page window not in focus" or something - it went away pretty quickly. So I just assumed it was not going to do anything, I closed the app, closed the drawer, and tried again.
