Sorry, my english isn’t very well, maybe thats the problem. I try it again:
If i create a WYSIWYG-Field with ACF and call it in the template files with: <?php the_field('nameoffield') ?>
oEmbed doesn’t work. It only shows the video url.
But if i used the standard editor from WordPress and i paste a video url in it, the oEmbed works as expected and i can see the video on the frontend.
Tanks in advance!
