Shortcode/URL with the issue:
Any vimeo url from my vimeo account
I am running 8.10.28 version and it works pretty well. But, I have tried several 9.x.x versions and no one seems to work. I mean, the video is missing. Only the url can be found in the post. It is like vimeo url was a simple phrase.
It doesnt work also in backgroud editor.
More info: the vimeo urls only can be shown in my webpage.
But, as I have commented, the untill 8.10.28 (included) everything works fine.
I am interested in Pro features (lazy one seems to be interesting) but I suppose that pro options doenst fix this issue.
