Embedding does not work in block editor after updating to WordPress 5.7

Hi @senribb! Could you possibly share what [type of content](https://www.ads-software.com/support/article/embeds/) you were trying to embed? I believe that info would be helpful to debug this.

Hi @dhruvkb

Youtube, WordPress, SoundClud, Spotify, Flickr, Vimeo and all other embedded block previews are no longer working.

In WordPress 5.7, iframes will be lazy-loaded by default. Due to this change, embedded objects may not be visible.

Below(last paragraph of the post) is an example code snippet which would disable lazy-loading iframes that embed YouTube videos within post content. Try disabling lazy-loading and see if it changes.

Lazy-loading iframes in 5.7

Hi @aoixtreme

Even if I added the setting to disable Lazy-Loading to functions.php as below, the result was the same and the preview was not displayed.

add_filter( ‘wp_lazy_loading_enabled’, ‘__return_false’ );

By the way, on the edit screen of the block editor, if I hover the mouse over the embedded block, the following guidance will be displayed.

“Preview is not available.”

This issue is a quote from the thread above.

This seems to be handled at https://core.trac.www.ads-software.com/ticket/52768.

And that’s part of the 5.7.1 milestone.

I confirmed the ticket #52768.

However, I found the following description in the above ticket.

Disabling iframe lazy-loading (source) remedies the issue and results in expected oEmbed post display behavior.

Why did NOT the code I quoted (disable lazy loading iframes) improve this problem…

Anyway I also hope this problem will be resolved.

Hi @aoixtreme

Certainly, the contents of the above ticket seem to be a little different from my phenomenon are encountering (The browser I used is Chrome Edge, and Android Chrome). Assuming plug-in interference, disabling all plug-ins did not fix the problem, so for the time being, Anyway I’ll wait until the release of 5.7.1.

The upgrade to WordPress 5.7.1 has been resolved the issue.

Thank you very much.
