I use the infinite scroll on my site, and when I have instagram embedded videos, they are only shown on the first page of the index. When I scroll and more content is loaded, the instagram embedded content is not shown.
I guess you have to do some refreshing when scrolling and loading content, but I don’t know how to do it.
I tried the load more button in the preview and it doesn’t work either, it doesn’t load the instagram embedded content.
Something similar happens to me also with the adinserter plugin, this plugin is supposed to support infinite scrolling, but is only able to insert content on the first load of the page, when we scroll and load more content is no longer able to detect it.
