The vimeo widget is working fine in Firefox but not in Opera (the two browsers I use most). The display image appears blurred with no play button. YouTube widgets working fine in Opera.
Please share the page URL where the issue persists.
Sorry for not doing that. Here’s one page https://tapestryopera.com/inside-opera/ but it is affecting all Vimeo sidebar widgets viewed in the Opera Browser. I don’t know how long it has been an issue as I only have been checking the site with Opera for a few months (due to its increased popularily lately).
