Hello,
I have noticed in T4 Blank that there is not open graph info being included on page sharing. Some networks will find the page title, but not the correct article image.
I have seen on some of the premium templates that OG info is included in custom page payouts.
Can you please include OG support in T4 Blank? Some frameworks give option in admin to "turn on" in template settings- and OG info is loaded for core Joomla menu items (article, blog, list, tags, etc).
Thanks!
