Thumbnail for Vimeo videos “only” on sites I choose

Hi Si Team

Psssssst this is possible one for Arlex

Previously I had a workflow that would enable me to post vimeo videos only my site:

https://stackideas.com/forums/posting-vimeo-only-on-sites-i-choose

Every thing seems to be working after moving to Vanilla except the thumbnail.
The thumbnail is one that is pulled when the SI Component can not pull a thumbnail from video.
I believe that the location of this thumbnail has changed relative to Vanilla.

If you login as a (normal) admin at the front end and go here:

https://www.finalbug.net/groups-learn-post-production-socially-fcpx-and-more/34-fcpx-foundations-videos/videos

You can see how this does not work.

Please see screen shot 01 and imagine that all of those empty boxes are filled with a thumbnail.

Please see screen shot 02 for how this thumbnail should/could look?

hope this makes some kind of sense

best

Paul
