Adding Vimeo video to Section pro?

Am I missing something in the Vimeo settings?

I’ve added the video the SP child video stack in the usual way, but it’s not appearing, just a blank space. I’ve tried with a locally hosted video and it’s working, so it’s clearly a Vimeo thing.

I have a paid-for Vimeo account, although hardly ever use it.

Help!

For Vimeo Pro accounts you should be able to get a direct URL to the video and use it just as if it were locally hosted. I know of at least one user who has used it in that manner.
