Just +1 this for visibility. I have a site with dozens of HTML embed codes in the posts that we are moving over to ACF Embed fields, and after editing around a dozen, the thumbnails stopped working on the backend, and on the frontend we just see a URL link and not an embed.
As a final followup, it does indeed wok fine using get_option();
This made me think ACF wasn’t initialized yet, but this quick test works fine in the same place of code:
if(function_exists(get_field)) echo ‘acf init’;
For reference, all other field groups on all other pages work without exporting to PHP. This only happens on any options page I test.
Is this fix going to be implemented in an update, or do we have to edit the core plugin every time?
