Hi There
I have this problem when posting my blogpost to Facebook - The thumbnail doesn't show up(ohh,wait, my website logo does show, but I don't want that). It doesn't matter if I use the autoposter or if I do it manually - it just shows my logo and not the desired video thumbnail..
If I do it whithout using the featured media widget and just paste the code from youttube, then it works like a charm - but then the responsiveness of the video disappears.
I've made two test post:
WITH media Widget:

debugging it on facebook gives me this

WITHOUT Media Widget:

The debug report shows that there is a Open Graph problem.
>>Inferred Property: The 'og:image' property should be explicitly provided, even if a value can be inferred from other tags.<<
I really don't know what this means.
I've searched and read the other post in the forum and a solution to this is nowhere to be found. I hope you fix this soon. I think this is a theme problem and not a WP or FB problem.
best regards
Christian
